I'm not exactly familiar with much of it to be completely honest. But if the electrical side and tuning side of things aren't causing a misfire I'm guessing id be looking at a mechanical issue. As you said nothing out of the ordinary that would cause a misfire on the log. I'll be digging into valve train next, will try to post an update after. Thank you for your inputs.

Ive tried swapping the injectors, misfire stays in the same cylinder. If it makes a difference it has this code, dont believe it ever had it prior to this. ECU Fault Code 122: Injector Duty Cycle above Error High Value

Hey there gents, currently having an issue diagnosing a misfire on cylinder 3 in my Beams swapped AE86 with ITBs. Little bit of a backstory on how it happened. Saturday night, a friend and i went cruising late at night, hit some backroads and did a bit of "spirited" driving. Car was performing great for the whole night, always kept an eye on all my parameters nothing unusual. After about 5/6 hours driving I heard a noise coming from my engine, a ticking of some sort. To me it sounds like an exhaust leak but cant verify. But at idle it was running rough and you could hear a bit of a misfire from the exhaust. After that i decided to call it a night and went back home. On the way home the car ran out of gas (no fuel level currently) and it just died on me, after putting 2 gallons of gas it started back up and kept driving. Drove me 40 minutes home no problem, even while running on 3 cylinders, no loss of power or anything. Now im in the garage trying to fix that misfire then address that ticking noise i hear. So far ive checked compression on all 4 cylinders, All around 155 but cylinder 3 is at 170. Not entirely sure if that will affect the way the cylinder misfires. Checked for spark, swapped coils, checked injector pulse, did continuity test on both signals for coils and injectors. Power and grounds checking out as well. Now my question is if anybody can help me check out a log file i recorded and see if you can spot anything out of the ordinary as im just a hobbyist and dont exactly know the software. Ill attach both my tune and the recorded log of it misfiring. Anything else i can check to eliminate certain factors out? Just want to get back to driving lolLorenzo's Beams 86.pclx Misfire Cyl 3 3SGE 86.llgx
