Sputter Problems when Car Heats up after 15-20min
I just got done with my b20 swap, and after about 15-20 minutes when I throttle it in about lets say 2nd or 3rd gear from like around 0k-2.5k it sputters. I tried advancing the timing, before it used to be around u 0k-4k. Now that I have advanced the timing all the way, it sputters around 2.5k and just straight up launches me. Anybody know what could be the problem ?

That's what I was thinking. I thought it was a bad dizzy too.
Because the 4th cylinder is getting barely any spark.
firing order
plugs and wires? if the sputtering changes by timing then it shouldn't be fuel at all. I would see if anything is wrong with those and move back from there. also check and see if the spark points on the rotor in the distributor are corroded or broken.
WHAT OCTANE GAS ARE YOU RUNNIN
My problem was fixed, the problem was that the PM6 ecu wasn't as quiet good as the PR4 in which I am running right now, just for further reference.
