I replaced the cap/rotor, they were looking to be due. The plugs are good, and coil tested good. The timing is correct. I also checked the tps, it also checks out. As well the fuel pressure regulator, it holds vacuum and no fuel smell out of it.So heres my suggestion updated
You must check and set base timing that is imparitive. Id Set the timing to 12* base——>That is with the spout plug removed.
Ohm coil to ensure its within range.
Check that plugs are correct ones and gap plugs to .052
Check that the plug wires firing order is correct.
Check cap n rotor.
inspect plug wires.

After changing the cap it improved a bit, the idle is lower and steady, but it still cuts out under hard acceleration. I videoed the tach as I drove. To show what I'm having going on. Waiting for it to upload
I'm wondering if I'm having a fuel pressure problem, or need larger injectors??
That I did do tooI would clean the maf meter as well with sensor safe cleaner if you have not already done so.

Video of the car, it will accelerate fine if I roll in smooth and slow, stumbles when you push it
Yeah, they are Accel #19 injectors. I'll try it with the regulator bypassed. I was thinking of running my fuel pump at 18v and see if that helps any tooIf its running lean it “should” throw a code.
It could be running out of fuel under hard acceleration. Try the unpluged vac line like i mentioned and drive again. If it improves then id say it needs more fuel. Your injectors are orange so i would assume they are 19# injs and it appears to be a stock fuel regulator. You are well beyond stock with heads intake and headers exh etc. i dont know if its cammed or not. Id say you likely are lean.

I will look at that tooI had a problem similar to that. The pick up was bad and loose inside the distributor. With the cap off you can look down inside the distributor. The part the rotor sits on has square windows cut out of it. There's a pickup that reads those windows. Take a small screw driver and check to see if its loose or disintegrating. Mine actually turned into a dusty white chalky mess. The car still started and idled but I couldn't get on the gas hard.
I believe the pickup is what the computer uses to keep the spark plug fire and timing correct. If I revved moderately it was OK.
I picked up a fuel pressure gauge, and filter, also new tfi and pickup, but with the holidays I haven't had a chance to do anythingAny progress?
