Engine Performance problem
1996 Chevy Corsica 6 cyl Front Wheel Drive Automatic 105000 miles
3.1, cold start, not much for fast idle (even below zero) drives fine until warm. After warm, idles ok and runs good at no or low throttle, starts hesitating and bucking as throttle is opened and load increased until tranny downshifts to high rpm at which point seems to clear out and run well until upshift and load increases. Then starts the process all over again. Can maintain steady highway speed if gas pedal is feathered once up to speed while maintaining low rpms. Easier done in D rather than O.D. NO check engine light or codes on an inexpensive scanner. New plugs and wires when I bought it 10k ago. Issue seems to have gotten worse with time. Anything I can do without a spendy scanner?
have the same problem?
