88 spfi 4wd d/r 199,000mi , it will start fine and warm up good, i then will move the car , set the parking brake and the car will die ? but not all the time ,new plugs, wires, rotor, /cap, all fluids good,

What happens when u drive it and get it to full opperating temp. And how does it drive, does it have full power.

Either a bad coolant temp sensor, a loose vacuum hose (at the airbox), or a dirty Mass Airflow Sensor (if your 88 has one). Those would be my areas of interest for the symptoms.

If all above fail to fix, the punt is the Idle Air Control valve on the throttle body (remove and clean).

power seems alittle low, but it does not do it all the time, + mpg has been low lately

thanks

Yea, when u warm it up, how long do u let it idle. idealy u should let it idle for 5 minutes at the most, unless its really cold out. not good to idle for long periods of time. U could be loading up and running with fouled plugs. But it kinda sounds like a MAF problem. there is a procedure for testing it in the hayns manuel. On sertain terminals if u back probe with a multimeter on ohms setting, and blow through the MAF in the direction of flow the reading should go up. I think. Its been a while scence ive done it. But it should be in the book.

new plugs , it has been pretty cold out , 10-15 above 0, at night ,and it does set outside , will check it out when i get home saturday morning ,thanks
