Hello, My car has been misfiring for awhile when I give it a lot of gas, but recently it has been idling rough and before it never did that... at first I thought it was the fuel filter so I changed that but there was no difference. I am wondering if anyone has any sugestions

 

whens the last time it had a tuneup? is the check engine light on?

 

^^^^^^^^^^^ also, what kind and year of car?

 

I havent had a tune up in well since ive got the car and that was a long time ago.

Its a 1998 chevy lumina 3.8

besides the new fuel filter i put in today I havent done much besides oil changes.

 

to describe my problem a bit more... when I am driving if I go at a slow speed then usually everything is ok, when I stop I started to sound like it wants to stall a bit I can feel it in my petal. And if I gun it then I loose power right away and here it misfire or whatever its doing... the check engine light also flashes at some points.

 

I would check the vacuum lines on top of the engine. Look for broken lines (this was my problem) or loose lines. Ended up buying a new part for 26 dollars from chevey.
