View Full Version : Intermittent rpm

01-21-2005, 07:03 AM
I have a 5th gen 1990 gt auto-trans with 180000 m. Everything is fine in the engine, but when in parking I accelerate and in the tachometer shows 2000rpm, the tachometer began intermitent to move up and down until I incremented the acceleration. The problem is just when it touch 2000 rpm. No more no less. Somebody ... with any idea of what is the problem.. please..

pd: Sorry my grammer . English is my second language.
