#5 cylinder header glowing
Hey guys, I have a 1988 gta ,a new zz430 engine ,hsr intake 24lb hr. injectors ,msd 6al box ,it has about 1 hr. of run time why would the #5 header glow? I've switched injectors, plugs, checked valve lash, checked for vacuum leaks, checked injector pulse , set timing to 10 deg. I'm stumped !any suggestions?

Gotta be running lean in that one cylinder. Injector or vacuum leak.

Inj hanging open and burning fuel in the exhaust?
Fuel psi regulator diafram ok? Not sucking fuel through the vac line?

Re: #5 cylinder header glowing

A stock 350 chip is better than the hypercrap..
