    does the engine always restart?, does this happen all the time? cold or hot engine? any system trouble codes present in memory? Check engine light on?

Most likely ETC Electronic Throttle Control. Some cars with this problem will run in drive but stall in reverse. Some will occasionally run but stall at stop signs or traffic lights.

    Run the Diagnostic test to check for error codes by doing the following:

    To check for Diagnostic Trouble Codes stored in the computer, turn the
    ignition on, then hold down the OFF and WARMER (for digital dash) or
    OFF and passenger-WARMER buttons (for analog dash) or OFF and "Info ^"
    buttons (if you have temperature dials) until all of the dash lights
    come on. The digital display will then show any codes stored. Be
    prepared to write them down. When it's done, you will probably see
    "PCM?" At that point, press the OFF button 3 or 4 times until the dash
    goes back to normal, or just turn off the ignition.

    Post back with any error codes you got.

My car is sputtering and dying. If I try to restart it, it will immediately go into sputtering/dying mode. If I wait a while an hour or so it will start up and drive fine.


When was the last time that the carburetor was stripped and cleaned? Also have you checked the fuel filter? Finally, the problem seems to come and go as the engine is run (and it gets hot) check that the fuel line and any electrical cables are well away from the hot engine as far as is possible.

Sputtered out and now it won't stay running; dies when put in gear.


Mass air flow , crank sensor . I wouldn't discount anything . Having a scan tool that can view engine sensor data would be a great help too , testing fuel pressure and flow and back pressure test the exhaust .

This could be a blockage in the carburator,try to clean it, especially the valves. There is a specific spray for the job on the market. You might need to dismantle it.

1988 Cutlass Calais. Motor runs fine on start up.


Sounds like the veh is loading up on fuel make sure coolant sensor to computer is reading right it could be choking the car.Also check for clean throttle body But what the most likely cause is the mass air flow sensor. Blow it out now do this gently there is a wire in there thats what you want clean. dont spray any liquids on it THANK TIM
