This can be caused by any number of things I'm afraid, from the mass air flow sensor to fuel injectors to vacuum leaks to a fuel pump. It really needs to be diagnosed. The technician will need to scan for any trouble codes and perform a proper diagnosis. It sounds like this is mainly a problem once your van is at operating temperature, and only bogs/stalls under load. All of that information can help a technician figure out what is going on with your van. Is it only accelerating from a stop? anytime you accelerate? What is the outside/ambient temperature? Does outside temp matter? Does it only happen when the engine is cold? only happen when the engine is at operating temperature? When it bogs, do you see any black smoke from the tail pipe? I'm sorry I can't tell you exactly what is going on with your van but I hope this will point you in the right direction.
I have a similar issue with my 1997 van. It seems to happen more when it is cold and the moisture in the air is higher. I did a complete tune up also and it went away for a while, but the issue has returned. Just as an indicator do you also have the exhaust leak at the manifold? When we pulled codes before the tuneup it was stating O2 sensor and Throttle Position Sensor warnings, but that they were still functioning. Not sure if this helps, but maybe we can determine out what the problems is together.
Thanks Andy, that help alot it does it from a stop and acceleration. If I give it just a little gas at a time it will slowly accelerate ok. I I try to accelerate to fast like on an on ramp it boggs down. It only happens when the engine is hot. when cold it seems fines. the outside ambiant temp doesn't seem to matter.
