Guys...I cant get rid of this problem.
I keep fouling plug #4.
Idles fine - new coilpack / module / wires. You can rev it in park with no missing. Put it in drive and try 'n build a lil boost against the brake - it misses on #4. Even when you drive it round the block - she misses terribly.
Pulled all the plugs - they look great xcept #4. Its got a black sooty (dry) coating.
FP is at 40 PSI line off now. I upped it from 35....didnt change the problem.I got the stock fuel pump in it still but the Walbro 307 is here waiting for install. Pressure holds at the rail after key off no problem.
What next guys ? Could it be an
injector ? Fuel pump ?
