stumbling stalling.... in an auto???

[oneslow30]

Well, got my 3 liter runnign decent..now when I drive it, it stumbles when it is slowing down,kinda bucking, liek the gas is stillpressed down while I am slowing down, then it stumbles and abotu dies,or DOES stall once at a stop...
now,I know that speed sensors were an issue in my old VNT Comp car.. this sound like the same deal?? in my v6 auto??
thanks in advance..

I'd check the MAP sensor. My Spirit had those symptoms way back when, and that was the cause.

Hmmm, interesting thought, and that WULD be load dependant (as in in nuetral or in drive) then wouldnt it? hmmm, could I use one off a 2.2 turbocar?? buddy has abotu 15 stock oneslaying around to go with allthe ld harness'

Which transmission? 3 speed or 4 speed? You need to tell us in order for us to help you.

[oneslow30]

Well, guessing 4 speed, as its OD, 3, the L

i had a 2.2L do the stumble and buckitis with a bad O2 sensor and a leaky fuel filter lol

[oneslow30]

but whats weird,its only stumblign at idle. and it dowenshifts hard when its almost at a stop, otherwise, runs like a raped ape

[Boogieman142]

downshifts hard, get ur tcm updated, if its like a hiccup at idle then u may as well get used to it.

Gotta buy a new module or Mopar need ot flash something? expensive?

[Boogieman142]

it can be reflashed depending on the year. To get it re-flashed it will cost about 60-75. a new one will be like 200-300

when I called the dealer on my 94 3.0 604 and 543 they said that they can't re-flash those at all. Was he full of it?

[Avenger]

Yeah, but they may not have the connectors anymore. I got my 94 Spirit re-flashed twice, with the 97 update and the 2000 upgrade. The 543 doesn't have anything to flash!

You can't use a turbododge Map.

Check your speed sensor.
