cars acting funny

MMMazing07 · 03-19-2008, 08:06 PM

Im not sure whats going on. But when i accelerate it doesnt go as fast as it used to.The RPMs take forever to get to redline and when im at 6-8k rpm there seems to be much less power than before. It also sputters alot when i let my foot of the gas at a high rpm. Just had a oil change at 10k miles.

I was thinking either
-Diff fluid
-Filter?
-Tranmission fluid?

Not sure

. Feedback please

my first thought was fuel filter. . .

Air filter?
Fuel Filter?
Spark plugs?
Your butt getting used to the power?

no Im pretty used to the power. Its just when i had not driven the car in a while i was shocked by how much power was lost. Usually i have a huge grin on my face after a period of not driving her. The car just doesnt want to go. When should/was the air and fuel filters be replaced?

I dont know what BMW recommends, but the one in my E46 at 50k and it was BLACK.
I am considering to do the one the Z4, but I don't have time right now.

Also, I would just start off by using some of that fuel/fuel injector cleaner and see how that helps.
