It appears that the problem is in the brushes in the alternator and the slip rings. At high revs and 4000 will be around 6000 in the alternator the brushes are floating off the rings. I would have the alternator check out

2000 pontiac grand am 3.4 motor auto trans 4 door.Car starts and drives okay motor seems to stumble slightly between 3000-4000 rpms. with car stopped in park try to rev motor will only go between 3200-4000...


Hi Tom your vehicle is equipped with a Rev limiter it will not allow you to rev the engine above 4000 with the trans in park; as for the first problem you may have one of two things, one of the spark plugs or spark plug wires is bad or you have a flat spot on the throttle positioning sensor in which case have be replaced. Good luck?

My 2002 dodge durango hits 4000 RPMs and bounces between 3000 and 4000 RPMs when I am in park and have the throttle held down. I replaced the cam sensor and it is still doing it.


this is your rev limiter stopping you from over reving engine causing internal damage. this is normal on all new vehicles. Don't know what year they started this but it goes back at least 16 yrs

Engine cuts out and sputters at 4000 rpm. sometimes hard starting. Quad 4


cutting out and sputtering at 4000 rpms are normal, its the rev limiter kicking in, all of them do it, as far as hard starting, is it just sense its been cold?? might want to put some fuel stabilizer in it.

My 2001 monte carlo misses out, no engine lite is on.


The rev limiter won't allow it to rev above 4000 in park. Will it go above 4000 on the road. Does it miss at ldle or under a load.

93 chev silverodo missing on 2 cylinders


This could be a few things. The first thing i would check is the firing order as 2 crossed leads will cause this . If this checks out ok try a compression test. A blown head gasket between 2 cylinders will also cause this. Hope ive helped

Check for a vaccum leak at the intake. With the engine at idle spray a bit of starting fluid to find it. You will hear the engine pick-up when you hit the spot. Change the necessary gasket. Hopefully this will solve your prob! Frankster016
