Replaced opti, icm ect, still having issues, help?
So i have a 1994 Camaro Z28 A4 and about a month ago ive had an opti failure, so of course i went and replaced that along with plugs, wires, and coil, the plugs are NGK TR55's and the car ran great, the opti was an Oreilly's brand. But i was left on the side of the road not even 2 weeks later, so i thought oh man shouldn't of got that opti, so i then went and got an AC Delco optispark, replaced that and it wouldn't fire up, turns out the ICM was bad, so simple enough i went and replaced it. i come to find out my rpms were 200 too low at idle and my transmission wouldn't kick down, my friend thought it was the TPS so i ended up replacing that sensor. I thought it was the computer not reading the ICM right. So i disconnected the battery waited 10 minutes and plugged it back in, it then ran fine. i did a couple of pulls and drove around a little bit, but then the idle is again too low, im running about 500-600rpms at idle im usually at 800. then the car seems to feel laggy or doggy, like its chugging a little now.
Would anyone have an idea what i might be missing? anything that could be the problem? its like the timing was retarted but thats impossible since its a splined opti going in only one way.
I also did the coolant bypass while i was doing all this, car also has headers, no cat and flowmaster muffler, no egr, and no smog.
