My 1994 chevy suburban will start and idle fine but after it warms up and i push on gas it spudders and dies out and will not start until it cools down

SOURCE: 94 chevy suburban revs up and down, then dies

timing chain

SOURCE: Vibration when in gear, and stalling.

The problem is the torque converter solenoid. I had it happen on my 94 Cavalier a few years back and was a cheap fix at the local car mechanic. What happens is the transmission warms up and hits a certain speed where the solenoid engages, but then it sticks and won't disengage until it cools down sufficiently. When it sticks, it causes the car to shake when slowing down and will snub out the engine if you come to a stop.

Check for vacuum leaks. Also try cleaning the ISV.


If that doesnt work go to vwvortex.com and post your issue there

I would start with cleaning the throttle bore and plate. Then clean the Idle Air Control valve, IAC, as this is the device that controls idle speed. Use a can of spray carb cleaner and an old toothbrush. Trouble with the IAC would make sense if you can keep the engine going by holding down the gas pedal a bit.
Use the carb cleaner to check for vacuum leaks at hose connections and elbows. run engine and spray short bursts at hoses and listen for idle speed changes.
And lastly if problem is still there check MAP sensor.
