Hey guys,
My 93 (5 speed, 66k) was running great after the H/C/I install last year. The problem was that my timing was either set at or skipped to 30*. I can't remember. I upped the fuel pressure to 50psi like an idiot.
The car started backfiring. I brought timing back down to 14ish (realizing it was at 30*). I also dropped the fuel pressure back down at the same time. It hasn't run since.
It sputters and backfires through the intake. Blows through plugs just going down the street. Smelled oil and it smells like gas.
I have found a couple of of posts on some forum that says it's one of 2 things:
1) The harmonic balancer is toast
2) Way too much gas is causing such a high initial timing because it takes longer to burn it all.
(My friends and I suspect that I blew the diaphragm on the FPR.)
Cam was installed dot to dot. No leaks that I can find. Vacuum lines are snug but not clamped.
Can anyone think of anything else before I blow money on another Adjustable FPR and a Harmonic Balancer? Am I on the right track here or am I missing something more obvious?
Thanks as always,
Strype
PS: This car has been sitting for almost a year since it was last driven. It either gets fixed or I trade it in pieces at the swap meet for a nice comfortable chair.
