the whole topic of optispark and other ignition problems seems to have been beaten into the ground a long, long time ago. im having some trouble and am looking for advice, because the threads on optispark problems are endless. also, i dont even know if i have an optispark problem.

when driving, if i mash on the gas (no matter what rpm) without downshifting, the car freaking stumbles a lot and does not accelerate quickly. the problem does not occur in first gear, and i havent noticed it in second. it happens most of the time, but not all of the time. the car has nearly 77,000 miles on it. any help would be appreciated.

thanks,
adam
