Hi first post, I have been reading the forums, and didn't find anything that might help, so here's my post.

Have a 1994 3.9l V6 (238) Dodge Ram.

It wasn't running before, then after checking a lot op thing ended up replacing the timing chain.
Now it running OK, but stall on idle IN GEAR. In neutral not so much.

Checked TPS, CPS, cleaned throttle body, IACV, checked cleaned plugs.

Looking for some suggestions on other things to check, so far i'm stuck.

Thanks!

 

Same identical problem with my 1996. Same engine, same symptoms. However, it only does it if the temperature is below 50 degrees. Let me know if you figure it out.

I just cleaned the pee out of the throttle body, be sure to check the TPS and that it aligns correctly.

And measure the TPS, CPS with a voltmeter, make sure they are within specs. They are cheap to replace so do if your not sure.

Not it's running fine, it's still and old engine, but no more stalls.

 

I changed the crankshaft position sensor CPS, and it instantly fixed it. It's running better than it has in a long time, now.
