why does my car stutter when i accelerate

Maybe your front cv shafts are worn and when you accelerate they become out of balance due to the tork of the engine then when you let off the gas they become balanced again, Get a non bias opinion from another shop. NAPA AUTOCARE CENTER http://www.napalocator.com/?st=ACMEC They can put your vehicle on the rack and check those front cv shafts before your warranty runs out

You may have gotten some bad gas.get afull tank, Mid grade or better. Add some fuel inj.cleaner every 6 months at least.And always consider a quarter tank to be empty. You could be sucking up old sedimate. especially if you have older metal tank.

Hey Bavenger. Just wondering if you got the answer to your question. I am having the same exact problem with my car.

I have the exact same problem but I can recreate it. BMW325XI 2005. Hit the accelerator. Around 50 Km/h in second gear at 4500rpm the car start stutter like if the clutch was slipping....I am heading to BMW service center as it's still under warranty. Defenetely not normal...

check your plugs and distributor, plugs can cause this they dont ignite right when they worn out (contacts/electrode on top), hope this helps :)

i would expect it to be a bad fuel pump or clogged fuel filter, when your in high rpm's the engine has a high demand for fuel and the pump might not be able to keep up. My friend had the same thing happen to his truck , under full throttle it would lose all power, then all of a sudden come back ready to go.

I have a 2004 325xi and have the same exact problem...after about an hour!!! why wouldn't it drive like that all the time?!? anyone have any idea?? i've had my alignment done & the car looked at numerous times...no one has any idea :(

I had the same problem after i took off my throttle body to clean it. my problem was that when I put the throttle body back on I didnt have the tps (throttle position sensor) on leveled enough. try checking your tps, or maybe it could just be a fuel filter needing to be changed, and try some sea foam in your gas tank too

it could be that the egr system is restricted with too much carbon

Just check your plugs and wires and distributor because you engine might be miss firing and isn't running on all cylinders.
