Beyond the afore mentioned checks, yes vacuum leaks can behave this way too, also check that all plugs are firing consistantly, an inductive timing light w/ RPM reading works good for this. Clamp...

When doing routine checks I have forgotten to re-hook up the MAF plug before and it behaves exactly like you describe, reving up then dropping, almost dying then rev up, on and on..... I suspect that...

I have a 90 MKIII front clip in good condition, and I'll probably never get around to doing the 1JZ thing. It was rear ended real bad, but the front never took a hit. I am curious about the motor...
