Stalling when stopping

[wheels]

It just started hapening recently. When i stop at a light, the truck will stumble and shut down. I have to left foot the brake to keep it running. Also when cruising on the highway, once in a while the truck will hiccup then be fine. Related? Any ideas?

Re: Stalling when stopping

check you map as well... same thing happend to me turned out to be the map sensor...

Re: Stalling when stopping

Both good points. I have a new 3-bar MAP from Detroit Turbo along with an Ultimate chip. Maybe i will throw my old 2-bar and stock chip in and see what happens.

What should i check for with the TCC, actually where is the TCC? I need to do some searching.

Thanks guys.

Re: Stalling when stopping

before you switch them out see if the map & ultimate are set properly it could be as simple as that....

Yeah i have had problems in the past with the chip not seating right, but everything is how is should be. I am thinking my ECM may be crap. but i dunno.

Any trouble codes stored in the ECM? A code 32 will flag an EGR problem.

Had this problem for a while... had no codes stored in that time. I'm running a 3bar w/ Nolan's tune on it. Does the truck lope at all when just cruising? At say 65 my rpm's hunt up and down almost like the truck is starving out

Re: Stalling when stopping

You guys couldnt give me these tips when i was having the problems??

I dont know what fixed it, i did a bunch of things at once. Reseated the chip, cleaned all the grounds, cleaned the battery connections, replaced some vacuum lines, fixed the purple wire..

I'm beginning to think it may be that my intake grounds run to the water neck... checked vacuum lines, rechecked the chip, etc etc. Of course, I don't have my truck here to work on so progress is slow :tdown:
