i finished installing my brand new optispark last wednesday and it ran perfect all of wednesday! even ran best 1/8 mile track times ever.. then thursday it wouldnt start. i realized that the ground wires on the coil bolts had fallen off so i reattached it and it turned over but ran like a dog.. feels like when you are off by a tooth on the optispark (94) is it possible for the opti gear to be in correctly but then fall out of timing? sorry if this isnt clear

 

Not unless it broke.

 

well i put the opti on wrong the first time... it was off by like a tooth on that drive shaft thinggy.. turned the car on and it ran like crap.. kinda like how it does now... so i took everythign back off, fixed the alignment with that gear thing, fired it up and it ran great! for about 24 hrs.. then the next morning it ran like crap again... i cheked everything i replaced the sparkplugs because the back 2 had oil on them, performed a compression test and all cylinders held 180-200 psi for 5 min each, checked plug wires and even replaced one... i have no idea what this is!! what are the symptoms of a bad ICM? or even a bad IAC or IAT? what could this be??

 

howdo i reset the computer?

 

Key off, pull the "PCM BAT" fuse on the panel at the end of the dash for 30 seconds.

 

ok well when i was testing compression i had the pcm bat fuse out for like an hour and still nothing... this is pissing me off... im gonna go to like sears and have them run computer diagnostics on it and see exactly what is going wrong
