at times engine will not start, loads up with gas. other times it runs great.
hmmm, get the trouble codes from an autoparts store of from a fifteen dollar scanner~...guessing the IAT sensor (intake air temperature) sensor is probably bad~
haven't been able to pull a code from it. when it runs, runs great and it's not showing any codes.
probably will not show any codes....adjusts the fuel at the temperature goin' into the intake plenum....cold there? adjusts the computer to enrichen the mix...ambient of warm...leans it out....see when warm it should NOT be tellin' COLD...y'see what I believe that problem is here~?
there is a wire what measures the density of the air coming in...cold air=more dense...etc.~
