plotting events for iac, timing, o2, rpm.etc right before it dies should indicate whether the ecm is misbehaving or whether the engine is. i would expect if its a mechanical or electrical problem that the ecm would be increasing iac to try to keep it running

So i have went now in the Advanced XDF and made a few slight adjustments and triple checked all option words, etc.

When in gear, it always shows "OD" on the whatsup display, no matter what gear, 1,2,D, OD, etc.. It's a 700-R4..... I increased idle speed commanded 100rpm in drive to 700... Before the IAC held in the 40's-30's steady....

It's just so weird.. It's never had a hiccup one when driving, once you pull out, or in Park/Neutral either it does fine, runs like a champ.... Just in idle in gear it will stall out of nowhere for no reason.... If you hold the brake and barley touch the accelerator it will stay running.... So i have made some adjustments..

Hopefully the small changes i made will have an effect and line it out.. I may crack the TB blades open just slightly more also... Double check TPS voltages at idle etc.
