Question about 1994 Pontiac Grand Prix
3.1 liter - I have run injector cleaner through it and have tried running a full tank of mid-grade gas. At highway speed (100-110 KPH) in Drive and 3rd there is a repeated hesitation - RPMs about 2000. If I accelerate, it downshifts smoothly and does not hesitate again until I idle down and sit again around 2000 RPM
