I just bought a 79 Chevy with the 5.7 350 in it..it was doing the same thing next time you put gas in it get some sort of additive like carb cleaner and put it in the gas then try and blow it out a little I drove mine about 100 miles when I bought it and it seems to be just fine now
1990 gmc p/u 5.7 wont idle showing code 12
possibly a vacuum leak, low fuel pressure, or the idle air control has failed,
check the pcv valve and hoses if there is a vacuum leak here it wont idle
Check the throttle position sensor or the idle control motor
Try to clean your throttle body. If you disconnect your battery or get a bad connection your throttle body will act up if it is dirty and it will not idle.
the idle solinoid may need changing, or its power source is not plugged in or working. If the solinoid is not powered the carby wont know where to idle, it will drive fine but wont idle when you pull up at lights ect.
Could be you need a new fuel idle motor. Or you need new spark plugs
i bought a brand new high performance carburetor, the fuel pressure is at six pounds but the car wont idle. it willl talke the gas fine bught dies if you let off the throttle?
Carb needs curb idle adjusted or rebuild.
Probably a bad idle air control valve.
The carburetor needs rebuilding.
Is it over heating? Does it have a clogged PCV valve? If neither of those maybe you have a fuel pump that's going bad.
time for a major tune up
The idle control solanoid is bad or dirty,could be hung open. the base gasket under the TBI could be blown or cracked. NEUTZ
Maybe you worked your truck a little to Hard. EASE UP on driving just a bit.
i had the same problem .. i got frion and put it in and it worked fine
Replace your thermostat, radiator cap and flush your radiator with pressure.
The issue may be one of several things. It may be caused by a clogged fuel line or fuel filter. There may also be a problem with the fuel pump, or a hole in the fuel line. It may also be caused by the fuel/air mixture being off.
try adjusting the idling level
its in the top end ..its the wrist pin that holds the piston to the crankshaft..but its fine just run the hell outta it ,it wont hurt nouthing cus its a Honda
no it wont to small of a starter
Timing Advance not working or fuel sensor messed up.
your truck wont idle correctly when its cold, because its cold...and nothing runs correctly when it's cold. your truck wont idle correctly when its cold, because its cold...and nothing runs correctly when it's cold.
check for holes in the casing around the engine that might be allowing water in the engine and flooding it.
