Having problems with your 1990 Chevrolet K1500 ?
My 350 tbi engine starts up, runs fine til it get warn, then it starts missing, chokes out etc.why?
\015 After it runs til the motor get's good and warm, it chokes out, missing will barely move, bbut when cold it runs fine.\015
probably Idle air control valve or EGR. under the dash there is a diagnostic port! with key off bridge terminal A & B turn key to on position (do not start) this will flash any trouble codes VIA the check engine light the first blink(s) are confirmation. then count blinks EXP,*** **= 32 , ***** ***= 53 , ** ********= 28... then just google GM OBD1 trouble codes and see what the problem is .
