Sup guys, I just rebuilt my block, but I can't get it to run right....it starts n runs, but runs nasty n it stalls.i changed plugs, wires,cap, rotor, fuel filter, etc. with no luck.....i got a 94 gt manual trans. Plugs are gapped to .044. I dont think it's an injector issue, im running the stock ones. I also tried running some rx7 ones,but it still misfires. If I let the gas pedal go it stalls. Messing with the timing doesnt help eirher.I tried looking for vaccum leaks by spraying starting fluid around the intake n manifold areas, but the car runs the same...any ideas what it could be?

This sounds exactly like my issue and I couldn't trace it either even after full tune up and properly gapped plugs. Also my engine was fully rebuilt 10K ago. Here's what solved my problem and it's kinda hard to believe it was the culprit.
That sensor in the pics (the one with the green wire sticking out of the top) sh*t the bed and caused my car to misfire, not start, backfire, and run like crap when it did run. Not saying this is your problem but it's worth looking into. The sensor only cost $40 too.
