    thank you for your answer but do you mean the wires on plug

    try cleaning off the cross wires in the bore of the mass air flow sensor (in the intake hose) and see if it helps any.

No...Inside the bore of the unit (where the air flows through), you will find two thin wires. In operation, those wires become hot changing their electrical resistance ...when dirt accumulates on them it serves as insulation. (they depend on air flow cooling them off to obtain a reading...more flow = more cooling and therefore different resistance value) To clean them use a Q-tip and carb cleaner and carefully wipe off any dirt. If cleaning does not help, there are tests you can do to check it (they can actually fail, aside from just becoming fouled.)

My 1992 Chevy corvette lt1 is not starting is getting fuel to the jet by the intake what do i do?


This vehicle should be fuel injected and therefore have no jets. If you are referring to a schrader valve on the fuel rail having fuel then maybe I can offer some help.You need to pull a spark plug wire off and see if there is any spark from the wire if you are sure there is fuel supply.Check for spark and let me know
