Engine Stalls When stopped and in Drive

I have a 1990 Chevy Astro Van It just started having stalling issues. it runs ok at high speeds but when speeding up it sometimes sputters, and at stoplights it will stall if I don't put it into neutral and idle up the engine . I have cleaned the roter and cap (they are only one year old), throttle body,replaced the inline fule filter I,m not sure where to look next its a 4.3 l engine with about 170,000 miles. Thanks for any help

Question, did you replace the throttle body, or clean the throttle plate, it will carbon up and block air needed for the idling speed to be correct. Also check for vacuum leaks, as the older vehicles didn't have good vacuum hoses. Good luck

I have1990 Chevy Astro van,it starts just fine,when it warms up,driving it or sitting still in drive or reverse, it stalls,I start it back up,in park or neutral,it stays idiling.Idles cold,stalls warm


Check the ECM grounds, they are under the passenger side kick panel. When the engine goes to warm status, the Oxygen sensors come on, If there is no ground on the ECM then it starts pulling ground voltage across the sensors and that causes big issues.

Continous surging and stalling


Per your description, I would suspect a fuel pump issue. When the fuel pump is running the pump impeller heats up. On an older pump the impeller can begin to seize up and momentarily stops and starts. Some times it just stops and has to cool down for a couple of minutes, then is ok for a while.
To test this theory, when the engine stalls and stops, your mechanic can use a rubber mallet and hit the bottom of the gas tank, this will free the pump impeller and the car will start again.
Or, have him install a fuel pressure gauge and go for a drive. If the pressure begins to fluctuate and drop, you know the pump is causing the issue.
Good luck, let me know.
Regards,

Sounds like dirty gas and the fuel filter is clogged...try changing the fuel filter...some are under the car, but most are mounted against the firewall in the engine compartment.

Stalling


Do this.
Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

1990 Ford Probe 2.2 automatic stalls in forward, reverse OK


Sounds like a bad IAC (idle air control valve/sensor) that controls your idle when going from throttle to idle. If bad your idle will act crazy and can cause stalls easily. Pretty sure that's it.
