Any ideas or experience with this would be appreciated.
My '97 Saturn stumbles on acceleration, 4 Cyl twin cam. When I step on gas pedal from a stop it stumbles once or twice before it picks up speed and runs good. Also does this when cruising at a steady speed and give slight pressure on pedal to just creep up to a higher speed. No check engine light or other dash idiot lights come on. Scanned OBD II and no codes.
Checked for loose connections at firewall and most anyplace I could reach, just wiggled wires really, not very in-depth testing. Could really be anything I guess but hoping someone might have some experience along these lines. Personally I'm thinking fuel related. Could be fuel pump relay or pump or computer perhaps cam sensor even throttle sensor I suppose.
I could spend a lot a money swapping out parts with out knowing the cause. I have a company van I use during the week so I guess I'll just drive locally until I figure this out. Have SAFECO road service so I"ll run it and see what happens, get towed in on them if need be.
DUH Just thought of this - I'll get some Lucas Injector cleaner. I would think if it was an injector I would be getting a check engine warning light though.
