Audi A4 Power Loss, jerking, cutting out Hi I'm new to this forum, as far as posting a new thread anyway. This was initially very intermittent, and usually when running a bit warmer After about 20 minutes of driving but gradually got worse, and when running cold Starting up didn't sound very nice!

Drove away Once again, i called, argued again and they said i had to bring it in ASAP due to the light. So another argument, with me saying that i wasn't convinced they would ever repair it due to them failing to do so two times already, plus at a rather large sum of money to me too, and they said they it could of been any of the parts already replaced that went down, and i argued again why i was paying for all three parts when they should have diagnosed the faulty one straight away.

Drove the car away for the 3rd time, and all seemed great. It drove really well as it used to and i was finally happy-ish. Then two days later, pulling away from a roundabout, getting up to 3rd gear, sudden power loss again, lots of jerking to the point the car virtually stopped and nothing would happen.

I had to pull over, hazard lights, turn it off and re-start the car and then it was fine again. Another two days later Approx. No lights have come on or anything, just no power, jerking, stopping, some smoke and the only way to get going again is to restart. I know they said they do it for free, but i'm loathed to go there, only i may not be able to contain my anger and drive the car through their showroom window.

But it would be nice to go there with some top tips, possible solutions, and or least some comments from others who have experienced similar problems. Please please please can someone shed some light on what they think the problem could be, and why Audi are so useless to finding out the problem themselves. Any help would be very very much appreciated, thanks. SteveSmithMar 29, Hi Mate, i'm in a very similar situation. Realiste1Mar 29, Do you have the sinking feeling that the horses under your hood have turned into ponies?

Does your four-banger feel more like a three-and-a-half-banger these days? If so, you might have a power problem. Back when carburetors were king and fuel pumps were mechanical, power loss usually came down to vapor lock or a clogged fuel filter [source: Goms ].

Today's intricate fuel systems have largely conquered the former if not the latter. Even so, all that complexity brings with it a slew of potential failure points. The same goes for the car's air intake and exhaust systems, particularly since catalytic converters became standard equipment in the late s [source: Newman ].

In many ways, though, the old rules still apply. Like your own body, every car needs fuel to burn and air to breathe. Your vehicle doesn't like running in high altitudes with a potato crammed up its tailpipe any more than you would but, hey, to each his own.

If only nailing down the causes of power loss were as simple as a tuber in the tailpipe, we wouldn't make such a hash out of diagnosing them. But identifying a power problem can try the patience of a saint, and doubly so when the drop in oomph occurs intermittently, virtually guaranteeing that your mechanic won't be able to reproduce it.

Car loses alot of power in third gear.

I have done a boost leek test a couple of days ago and it held 20psi for about 1. So I don't think that is the problem. I think it might be the cat. I know my profile says I have a 3" test pipe, and I do, but none of the exhaust parts are on the car yet. Sep 26, 6. So nobody here has any idea what this could be. Sep 26, 7. Sep 27, 8. Sep 28, 9. Some other thoughts: CatCon could be obstructed, exhaust manifold gasket leak, fuel filter clogged, intake leak i.Eddie spent 35 years in the automotive business with Honda.

We all know what an automatic transmission is, basically—very basically, at least—so I'm not going to bore you with the details about how it converts power from your engine into power at the wheels. But you should know that the process involves plenty of hydraulic fluid as well as gears and clutches. The cause of a slipping transmission will depend on the type of transmission you have in your vehicle.

I will discuss the two most common types, automatic and standard. If you have an automatic transmission and it "slips" while you are driving it—that is, the car engine revs without the power going to the wheels—the most common cause though not the only possible cause is low transmission fluid.

If the slipping is caused by low fluid, it will get worse as the transmission gets hotter. The next question is, why? Probably because you have a leak. The cause of your leak is probably a failure of one of the seals that keep the oil inside the transmission though there are other places the transmission might leak.

How many seals the transmission has depends on whether you have a front-wheel-drive, four-wheel-drive, or rear-wheel-drive car. Seals themselves are not expensive parts, but depending on where they are located, it might take a lot of labor to replace them. Axle seal failures are common, and the dealer will usually have those seals in stock. But if it's your input shaft seal, plan on leaving your car for a day or two, and expect the labor cost to be upwards of eight to ten hours.

This photo shows an input shaft seal leak. To replace this seal, the transmission needs to be removed from the car; this job can get costly.

If your transmission is leaking, you will want to fix it. Meanwhile, if you must drive a car with a leaking transmission, you should top off the fluid. Some manufacturers will want you to check the transmission fluid level when the engine is warmed up and running with the transmission in park, other manufacturers like Honda will have you check it with the engine warmed up but not running.

If your transmission fluid level is low and not showing on the dipstick, add transmission fluid--the proper transmission fluid.

Each car manufacturer uses a specific fluid. If you use the wrong fluid, you could damage your transmission internally, so again, check your owner's manual. Fill it to the top line on the dipstick and then drive it to your mechanic. Note: Sometimes when an automatic transmission is low on fluid and you top it off, air pockets develop inside the transmission that keep the fluid from getting to all the parts of the mechanism.

After adding the fluid, I suggest that while the car is running, you move the shift lever through the different gears on the shifter selector, and then check the fluid again. Running the shifter through the gears redirects the fluid to different parts of the transmission and removes the air pockets. You may have to do this procedure several times, or even drive the car around the block, and then recheck the fluid level.

Note : I do not recommend using additives that are supposed to stop leaks; they can plug up the transmission.One moment car was running perfectly, next, just loses power. Hi There, What you are describing sounds like you may have a clogged or damaged catalytic converter.

Bosch bandschleifer pbs 75 a 06032a1000 microfilter-system

The catalytic converter converts toxic exhaust gases into less harmful pollutants that are suitable to be expelled into the atmosphere. When the catalytic converter is clogged, this causes these gases to be backed up into the exhaust system not allowing the engine to breathe properly. When this happens, the engine is forced to work much harder to expel these gases. This often results in the engine bogging down, hesitating, shaking and causing very poor fuel economy. This should also cause a check engine light to come on as the O2 sensors should be reading the incorrect amounts of oxygen in the exhaust gases if this is your problem.

I would recommend having an expert from YourMechanic come to your location to diagnose and replace your catalytic converter. Q: 3rd gear and up, losing power after 3k RPM, can't get above 60mph, smells burnt. My car has miles.

StaceySky Posts: Forum Member. Hi, I have a Vauxhall Corsa 1. It's 10 years old. It's done 96miles on the clock. Runs on petrol. Manual drive Brought the car 4 months ago. I recently took it to Vauxhall for a new fuel pump relay.

However ever since my car is over revving whenever I accelerate but it doesn't gain speed. When I'm driving along the dual carriage way it takes ages to pick up speed yet the car is over revving. Cars are always over taking me, it's embarrassing.

I'm on the dual carriage way barely reaching 30mph at times. When it finally reaches 40 I up the gear to 4th. Thinking about it now the over revving seems to happen when i change gear. The car takes a good few seconds to gain any speed. I was wondering if there was a mechanic online who might have a rough idea of the cause. I know I will have to take it to the garage most probably Vauxhall to get it sorted, but I just wanted a rough idea of the cause and price.

However, a loss of power may also be due to an external factor such as high temperatures or other climate issues. Working out why your car is not always easy, so we should consider all the possibilities.

We also need to look at the circumstances when your car loses power to help determine the problem. If your car loses power while you are driving, there may be a variety of different reasons why. In this oneHOWTO article we'll help you diagnose your car's problem yourself, offering a number of possible answers to explain why does your car loses power and giving you some tips on how to fix the problem.

Your car may lose power if an injector has poor contact with the internal combustion engine. If this is the cause of the problem, you may also notice an exaggerated vibration in the motor.

The fuel injector is an appropriate name for a car part which injects fuel into the engine. The fuel needs to travel from the tank into the cylinder where it is burned and the energy it creates is used to propel the car. Fuel passes through the injector, but so too does dirt and debris which may get caught up in the engine system. As a result, the fuel injectors will often become clogged and dirty. A dirty fuel injector is one of the most common reasons for a car losing power when accelerating.

When we accelerate, we send fuel to the engine. If the injector is clogged, the reaction may be that the car loses power. We recommend that you maintain these parts well. It can be done by a mechanic, but you can also learn how to do it by yourself by reading our article how to clean a fuel injector at home. If the fuel injector is damaged for another reason, then they will need replaced.

This can be done at home, but it's a bit tricky, so go to a mechanic if you don't have much experience. If your car's model is among those which have a turbo engine or turbochargersomething that is increasingly common, you may find that this element is the reason why your car loses power when you drive. Turbochargers work by pushing extra compressed air into the engine which, in turn, causes greater acceleration.

It may be that a tube connector of the turbo engine is damaged, it is simply dirty or it has been poorly adjusted.
