2002 dodge van 3.3 se cranks ok,when put in gear dies,cranks ok put in gear drives ok,dies at next slow down.sometimes will not idle sometimes idles ok.when ac is turned on will die.cleaned idle speed senser. New fuel pump ,filter, plugs 103000 miles

 

You could have a torque converter locking up on you. I had this same type of problem with a sebring.I also would clean the throttle body blade and bore.

 

Tks how do I check for torque converter lock up?

 

Ps no codes

 

when you put the vehicle in gear, it dies is one sign of the torque converter locked up when it shouldn't

how does the car idle when you start it and it's in park or neutral?
when is the last time it had a complete and proper tune up?

 

Thanks for everyones help, bottom line,replaced TPS solved problem.
