I got a ZHP engine somewhat locally. I'll tear it down, inspect it, refresh it and slap it in. The original engine will be modified for more NA power... that's going to take a while lol.

She died on me today as I took her to redline in third. I was on the highway, airing it out, hit the rev limiter and got the same misfire code/symptoms as before. I'm thinking in my head that the...

I'll run the car for a week, if the misfires do not return, we can consider this case solved.
Racer,
I believe I have clogged cats as well. My ZHP spits out a lot of soot sometimes. I had my wife rev the engine to 2000 rpms, I put my hand by the tail pipe and the amount and pressure of the...
Fixed my fuel trims and MAF readings by tightening up the MAF pins, still didn't fix the misfire but I'll tighten up my other pins (coil, injector, DME) and see what happens. Compression is good,...

Luckily I have not had this issue reappear since I repaired my ECT sensor harness. Time...
Ahhh. Good to see someone much smarter than me already on the case. Seems like we have the same thought process, which is good.

VANOS seals

Seems to mostly happen in 3rd gear at around 6000 rpm. It's...
