#1 of 3 sluggish acceleration by deano2 Nov 13, 2008 (7:15 pm)
I have a 2002 Impala 3.4l and it seems to have an acceleration/power problem. It accelerates very slowly from a stop or at any speed. To get it to keep up with traffic it revs quite high. The motor seems to be working quite hard for normal driving. Sometimes up hill it wont accelerate even when pushed too the floor but it revs up. It also seems to be using alot more fuel then normal. Any ideas? Thanks. Replies to this message: nosirrahg (Nov 16, 2008 6:25 pm) isabella (Jul 18, 2009 7:03 am)

Replying to: deano2 (Nov 13, 2008 7:15 pm) if the engine tachs,revs but the car is not accelerating,sounds like a trans malfunction,check your fluid (trans). our impala blew the trans at 68,000 miles. symptoms before it happened ...put in gear engine revved up but it wouldn't move,same when leaving a light. I own other new chevy's they all have the same thing happen,trans flush every time its scheduled helps this prob alot. hope this helped
