so heres an update. i tried doing that iac reset procedure, and it seemed to work a little, but even with the iac AND tps completely unplugged, it idles lower however still surges kinda, just not as severely. but it doesnt stall even with the iac all the way closed, so im puzzled at where i could be leaking vacuum. the only place i can think of is between the 2-piece adapter place for the tbi., but i used a lot of that copper head gasket spray between them, but and the last time i took them apart it took 30 mins of gentle prying with a razor blade and tiny flat head screwdriver, LOL. but i might be able to rtv the mating surfaces. i still dont think they are leaking tho.
i took a test drive after i had unplugged the MAP sensor, as i was so frustrated i just started unplugging sensors til something changed, and with both tps and iac plugged in, but map unplugged, it ran beautiful. i mean the best i've ever heard this thing run. ever. so we drove it. still ran great, no surging, no dying, nothing. however, as expected, if i punch it at low rpms, it stumbles and falls flat on its face. but its still got instant throttle response otherwise. tried plugging a new one in, and back to the same bs crappy running. now im sincerely confused. cant i have the best of both worlds??? haha. thanks again.
