Stuttering 95 GT

Prdbyford1 · Mar 28, 2010

My 95 GT has developed a stutter when you are cruising (part throttle) at lower rpms. The engine is smooth as silk while accelerating. It has fresh plugs and wires along with a new distributer, cap/rotor, O2 sensors, and new egr valve. Any ideas? Thanks in advance.

LOL mygreengt. I knew that was coming sooner or later when I posted. Going to get some vaccum readings. What about a small hole in the stupid pipe from the egr to the header causing a leak?

that would be an exhaust leak tho not a vacuum leak plus there would probably be a ticking noise in that area when the car is running
