S13 KA24DE Misfire Under Load

[sadshins]

Update, i checked the fuel pressure from the pump, and its reading normal around 34Psi.
I then used a timing light, put it on all 4 plug wires and ended up with the same results of it fluctuating between 965-985... but what does that mean?? Ive never used a timing light hahaha super new to all of this

Fuel pressure is a little low but probably not the issue frankly. I would assume the 965-985 is the idle speed of the engine. An engines idle will fluctuate, this is normal. Was the timing mark on the engine correct with the light?

That is the RPMs, and those numbers aren't bad for idle at all. I'd be interested to see what the timing looks like through the rev range though since you're getting the misfire up top.
