Ok Guys, My second SOHC KA is taking a crap on me. It has been running really rich, car has a new fuel filter (6 months), and I was thinking maybe injectors being dumb. took them off, used the best 4 out of the 8 I have, put them back in, ran better. was driving around, I decided to redline it to make sure things were good. evidently not. Damn thing is running rich as hell and idles like a Top Fueler. I've reckecd electrical connections, I see no Vacuum leaks, I've re ground the MAF, I'm at a loss. I'm gonna go get some new PSpark Plugs and another Z32 filter, but it seems like I blew a sensor or something when I floored it, and I dunno what it is, help me
