Fuelie loads up when cold--Help
i moved this over form the 73-87 truck thread. should have posted it here before, considering there are 3 more years of FI 5.7 and 454 burbs and blazers.
So with my '88 w/ a Throttle body FI bone-stock 454, it seems to run incredibly rich when cold and first starting. smells like gas and rolls smoke like unburned fuel (not oil) out the tailpipe. changed all the plugs (used E3 plugs) and cap and rotor--all of which seemed to need it. a couple of the plugs were black and carbon-looking, even up on the white insulators. it certainly runs better, but still does this when cold. it seems to straighten out and runs pretty good once it warms up. with an old school Q jet, i'd say its got a float sticking or an auto choke problem. with the FI, i have no idea. maybe a TPS or something like that? check engine light is NOT on. any suggestions appreciated. |

Re: Fuelie loads up when cold--Help
sounds like my tbi 88 350 when the choke stuck
at least thats what the garage told me....i'd start it cold ,and it would smoke like a diesel till it warmed up |
