Check air filter and replace fuel filter. If that doesn't work do a tune up (spark plug wires spark plugs). If that doesnt work then there is a problem with a sensor to the point that its within voltage, amperage or resistance settings programed in the PCM (powertrain control module) to not set off the check engine light. Or the timing jumped a tooth.
If the check engine light on get it scanned to see what the code is and investigate what the problem is.
It will overheat at idle.It will overheat at idle.
If it drives fine but dies without warning while slowing down I'd bet on ICM.
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
Check taillight/parking light sockets for corrosion short to ground

my 96 dodge Dakota wont idle when engine is warm and i changed idle air controle valve what else could be wrong
Idle Air control (IAC) Bad Idle Air control (IAC) Bad
try checking that there is no moisture build up in the sparks as this will cause it to idle rough but drive fine. if u do find moisture try spraying some crc 556 or other lubricant in the spark cavity and check the spark plug gapping. if its still idling rough after that take it to a garage :-)
You might need idle speed adjustments. Check and adjust your valve clearances. You might also have a restriction in the intake or exhaust.
Minimum of 10 psi at idle, 20-30 at idle is average.Minimum of 10 psi at idle, 20-30 at idle is average.
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.
it happen too my 01 dodge Dakota the sensor is beside the throttle positin sensensor
