Stumbling on acceleration

lowp51 · March 11th, 2009, 05:51 PM

Hey guys,

Stang started stumbling today when I was getting into the throttle. After a while driving, the stumbling stopped and everything ran well, engine codes kept popping up intermently. I think I have an ignition problem, new cap and rotor maybe. Pretty sure the codes are coming from bad O2 sensors. Anyone have any other suggestions?

was it "stumbling" when the engine was still cold? or had it been warmed up well? you need to make sure she is good and warm before you get on it at all.

it is most likely an ignition problem... but may simply be due to a loose wire somewhere since it's not consistent. def change those o2 sensors. that might help too.

Any of you recommend the performancedistributors firepower ignition kit, or should I just get a new cap and rotor, still going to get new o2 sensors. 5.0 Ignition Products

Pullthe codes to find out whats going on. Dont just start throwing ignition parts at it as that may not even be the problem.
