THANK YOU SIR!!!!!!
I’m watching you need to get that hot rod fixed I’m having similar problems. My problems started after I changed out the optispark. Car was running strong (my wife’s car) it quit on her put it in the shop changed out the opti, coil both MSD parts new computer idle air, throttle module, mass air, etc, like you throwing money at it. The car has never run well since, and all I did was change the distributor. I’ve had all my mechanic buds look at it and they just scratch their heads and tell me don’t bring it to my shop. So I’m watching!!!
Here’s to hoping that we both get ‘em across the finish line brother!! 🤞
I'm a proud owner of my 94 TA. that I'm building from the ground up.. alot of times the plastic fuel lines that run into the fuel pump get crimped and it blocks the proper amount of fuel to feed the pump... I have pics on my Instagram page of that problem at keith's 9809....

Should have told what the plugs on the coil are for
Lt1 opti u better roll a seven when u guess..
Have had ICM probs so look there first before u take the radiator out..
One time was ICM.. all the others was opti..
ICM had weird misfires midrange under light accel wud stumble, deteriorated with heat soak till car wud stall out, crank no spark..
Once it cooled wud run fine again till got hot then same thing..
Cost me a tow but eh whatever.. its paid for..
Get a cheap inline spark tester one that lights up helps a bunch u cud see what u got
