Could this be my Opti? the other night i was cruising and went from 4th to 6th and the car started hesitating and stumbling bad. no load not speeding just cruising. the car hasnt stopped running like cracp ever since! i replaced my FPR thinking it was that but it wasnt. everything is brand new fuel pump, filter, regulator, coil, wires, plugs, icm. no arcing no nothing. except for this sever stumble and hesitation. at idle its the worst. misfiring and popping. the exhaust actually sounds alot louder too. its odd because above 4k or so it actually runs alittle better but theirs NO power. the only part i didnt replace is my opti. does that sound like symptoms of a failing opti ? im going to try to find my multimeter and try testing it. any input would be appreciated.

im going to try to get my hands on a scanner asap. i dont want to bring it to a mechanic simply because its running so shitty i dont wanna try to drive it to one :x
it would take longer to start and run like absolute crap ? lol my dads 95 caprice had almost the same problem when his opti went. ill try getting a scanner and seeing what results that comes up with. ill also be testing the optis harness. shobox has a neat little walk through im going to follow hopefully later

hmm ill take that into consideration. its an MSD cap and rotor set. the screws came with that little bit of red stuff on the tip. i thought that was lock tite of some form. it would make sense. i dont want to tear down everything to get to the opti and have it actually be the opti unit itself that is bad. i dont have much time to waste with my car completely down for awhile
