maybe your not making enough hp to spin the tires and the cars doesnt like it. Try solids motor mounts. Do you have SOHC or DOHC? Your engine maybe be getting old and beaten and simpily doesnt have the juice to spin the wheels!

rico_20002

I have DOHC

Oxygen sensor, maybe.

At what RPM does this stumbling occur?

rico_20002

around 4-6k but only sometimes

if your car stumbles, its probably not getting enough fuel,
did you ever change the fuel filter?


my car used to stumble at low rpms but that was an ignition wire problem

My car stumbled above 3500rpm and had no power. I changed the oxygen sensor and it was fixed. That is probably your problem.
