    I have the same problem on my 1988 astro. I have replaced the MAP sensor, the throttle position sensor and the air management valve and the problem continues. Can anyone help out with ideas? Thank you.

signs of a bad fuel pressure regulator. the vehicle runs rough, the engine will not start usually in the mornings. many times engine starts but stalls shortly after starting. a bad regulator can result in fouled plugs. black soot on plugs, blake smoke from tailpipe, running rough, stalling. you could have residue in fuel tank and need to change fuel filter again. have a very good day !!

Van stalls intermittently. When we take it to a garage, they let it idle for an hour and it won't stall. We have already replaced fuel pump.

Lack of power


Try replacing the fuel filter. Get the pressure checked. Check the vacumn hoe going to the MAP sensor.

Engine Stalls When stopped and in Drive


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

YOU'RE GONNA HATE THIS BUT IT DOES SOUND LIKE A FUEL ISSUE. HOWEVER HERE'S THE CATCH.....THE FURL FILTER IS IN THE GAS TANK CONNECTED TO THE FUEL PUMP. YOU HAVE TO DROP THE TANK OR TAKE THE BED OFF TO GET TO IT. AND YOU CAN ONLY GET THE NEW FILTER AT THE DEALER. THE LOCAL PARTS STORE DOESN'T CARRY THESE. BUT I'M NOT SURE ABOUT NAPA, THEY MIGHT. YOU MIGHT ALSO WANT TO CHECK FOR A VAC. LEAK AROUND THE THROTTLE BODY. LASTLY WHEN WAS THE LAST TIME YOU DID ANYTHING TO THE TRANS.? MIGHT WANT TO LOOK INTO THAT.
