FIXED 05 Dodge Ram 1500 stalls at stop.

God bless you my brothers and sisters.
05 dodge ram 1500 4.L I rebuilt the engine new over size pistons, rings and bearings. When i was done putting all together i started the truck and it ran good. I let it idle for 4 hrs. and it nice and smooth idle was at about 600 rpms. Now I take it on a test drive and it runs great but when I come to a stop idle will drop to 500 rpms and come back up sometimes, most of the times it just turns off. I find if I come to a slow stop and lightly release the brake it will stay on. There is no dtc truck runs good only thing is idle at stop. What should i be looking at ?
Thank you for your help.

I would check for a vacuum leak involving the brake power booster. Can you hear a hissing from the booster while braking?

Pole 71 thank you for your quick response I hear no leak the truck does have trailer brakes if it makes a difference.

I was thinking the same thing. Especially if it idles fine in park without your foot on the brake, but then dies with your foot on the brake.

God bless you my brothers and sisters.
Ok if i step on the brake to shift it is fine if i come to a slow stop it is fine. When i'm doing 50 mph and if I need to step on the brake and come to a some what quick stop it will turn off. If i baby the brake peddle i can stop idle drops to about 500 rpm i release the brake peddle idle go's back up to 600 rpm. If i'm goin up hill and I need to step on the brake it will turn off, it's like the idle motor is to slow to respond .
Thank you for your help.

Yo gilbert! How's the transmission fluid level? This kinda sounds like the torque converter clutch is sticking applied due to low fluid level.

God bless you my brothers and sisters.
Brother Tyler onces agine you save the day thank you very much. The trans. was low it took 2qts. as soon as i filled it up and went on a test drive truck didn't stall at all.

Sweet! I've been beaten up by the same symptom before on a Jeep. It seems like most domestic transmissions will do this, but Chrysler products seem to be especially susceptible.

Nice call, Tyler!
