My car keeps stalling, I had dyno tune 2000 miles ago, 3400 stall headers new O2 sensors, and simms in the rear.
Idle is at 500 - 600, and drops below 250, when I come to a stop or put her in reverse. Pretty embarassing to stall out an auto.
Dealership says they cant raise idle. Or find the cause

Anyone else have / had this problem???

 

Might need to do the idle relearn:

Reset the computer by pulling the leads on the battery for 5-10 mins, then reconnect and start it back up and leave it idle for 10 mins with the AC off, then 10 mins with the AC on.

If that doesn't work, bring it back to the shop and get them to raise the idle. 500 sounds a little low.

try what kraest mentioned first, if that dont work, either get the guy who did the tuning or a competant mechanic to check the IAC. do a search on here for that. i had the same exact problem you are describing from a mail order tune. had to have the pcm retuned.

 

Tune just needs some tweaking, bring it back to your tuner. If the car is tuned never let a dealer connect to the DLC. If it's like mine just needs the in gear idle speed rasied along with the line pressure if it wasn't done previously.

 

Just tried the idle relearn ...Still the same. and SpeedINC is a long way from here. "bout 8 hours.

Thanks, Guess I'll have to get a hand held programmer.

 

Go to a local shop and have them raise the idle.

 

Man I wish it were that easy. Closest is 4 hours away.
I called diablo and they said a shop would have to put in a custom tune, because of my mods. I called as far as Detroit. and he said it cant be done for about another 2 weeks.. He's moving to a new location. still 4 hours from me.
