a few quick questions

You could try tying open your aux ports temporarily, then rev it up and see how it acts. If it runs better, then you know what your problem is.
Oil leak: it could also be coming from your oil cooler lines, they run on that side. Clean all the grime off, let the engine idle and look for leaking oil.
Also, no exhaust with just an open manifold? revving up to 3k? are you deaf yet?

soo took the car out again today. just kinda tied the exhaust ports open. just around the top. still horrible stutter. sounds like crap. and is the slowest car ever. kinda sounds like fuel cut but the injectors are good.
i have no idea waht to do.
the problem again is around 3000 ish under load. the car will pull hard till 3000 ish then get kinda louder as in higher pictched and not want to pull hard at all.

should i swap my secondary rail out for another one? im real lost on whats going on. i thought it was the 3800 hesitation. but my grounds are all good. and then i thought it was ports not opening. but after i wired em open i realized that it wasent the ports. so do you think its clogged injectors or is somthing else wrong?

i think its more likely to be the electrical connection, but possible that they are clogged or stuck.
step one is to unplug the connector (secondaries are on top), have a good hard look at it, are the pins backed out? missing? next, find power and a ground and just tap the injector pins (doesnt matter which ones) the injector should click. if it doesnt click they its not working. if you have to do more than once, you may want to pull the 'circuit opening relay' to disable the fuel pump and then start it first, as opening the injector with fuel in the rail, goes into the engine.
if you dont find anything amiss there, turn the key on and check the injector wires at the connector, the black/yellow wire should have power, if it does not then you need to find out why (if the car is 86-87.5 its prolly the injector resistor), the other wire goes back to the ecu, and should not have power or ground while the injector is unplugged.

its you cold start that makes it tac like that...as far as the backfire iv seen a few 2nd gens do it no biggie. but do put your manifold back on. your not gettin the right backpressure without it. sorry if its already solved im new. this is probly old
