1988 Dodge B-150 Van Stalling

I have a 1988 Dodge B-150 window van w/193,000 miles. It belonged to my father who passed away this yr. The van runs fine when first started and then after about 15 minutes it acts like it wants to stall when at a redlight, also if you let off the gas when driving it wants to stall as well It has a 3.9L V6 w/ throttle body injection. I have looked for vacuum leaks but to no avail. I know this is pretty general info but i am stumped. Any help would be appreciated.

You may have discovered by now... although it took me $2400.00 and six months.... change the Gas Cap. That simple. Young apprentice at the shop read up on it. The garage was so embarassed they refunded $1800 of the repair bill.

not saying it cant be that but a gas cap is a thing to check ..

i would NOT consider that to be a final solution based on what he has provided ...

My similar problem turned out to be the fuel pump. $25 at Kragen auto parts.

fuel filter ?? bad tb ??

vacuum leaks, what did you do to checl them ??

Bad ISC motor or vehicle speed sensor?
