99 chevy astro van chokes and stalls when you give it gas. it will also stall when it idles but not as fast.

Maybe fuel pump...check for trouble code...if no codes check fuel pressure

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.

If the engine RPM drops and does not recover, its usually a faulty idle air control valve. Can you keep your foot on the gas and keep it running when you come to a stop ? Is the check engine light on ?

is there a check engine light on? There are numbers of things that can cause this.

maybe your iac valve is not working? it takes place of a choke or temp sender to computer could be bad which controls t I.A.C. known as the idle control valve,do you have any codes?

WELL YOU CHANGED ALMOST EVERY THING EXCEPT IGNITION CONTROL MODULE........

Sounds like clogged cat converter.

I have had that exact issue on my 99 astro,but before it left me stranded on the side of the Highway it was running a little rougher than usual,but once accelerated it was fine,until it finally Stalled. So i Replaced the fuel filter and The Cap and Rotor and now it is Fine,started Right Up.

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

Right turn signal - activate turn signal and check to see if bulb (front and rear) are flashing. If not it will affect the flashing timing. Replace bulb. As for stalling, may yet be sediment/gunk in tank that is clogging new fuel pump filter and inline filter. Or an idle/throttle position sensor. Hatch problem, I've no idea. Family members 1998 Grand Caravan has been infected with similar gremlins in the sliding doors. Best advice is to obtain a Chiltons/Haynes repair manual and go through the troubleshooting section.
