HELP! Engine cuts out after fillup - NAJ!!!
Ever since lunch at work today when i went to go get some food, and filled my car up with gas (completely full),, my car has been acting a bit retarded. Whether in manumatic mode or just in regular auto, and with and without traction control on; when i really get on the throttle, the car falls on its face hard, the dash dings / beeps, and the check engine light comes on for a split second and then its gone and the engine starts up again automatically and it drives like normal again / no engine light on / like nothing ever happend
I ran my actron plus scanner model CP9580 and it gives zero codes.
It happens every time i get on the throttle hard and the closest thing that i can relate it too is when i boost my spirit r/t out of my ecu and map range and it hits fuel cutoff / sends the map sensor signal to the ecu for overboost protection. but the thing is / my 5.7 hemi isnt boosted (yet :P)
my car is a 2006 hemi r/t 5.7l rwd. with zero mods minus a reso delete and k&n intake
the car drives perfectly normal / doesnt cutout when driving it normally, with cruise on at 70mph, ideling, starting up, etc, ONLY when accelerating heavily
i know there is an issue when overfilling on the newer vehicles but everything im reading about overfilling is that raw fuel gets in the evap system causing hesitation or stalls at idle / when slowing down or starting / failing to start... I have found nothing about heavy or WoT acceleration stalls.
ran it with and without gascap on / problem persists.
grrrrr its aggravating when i actually fill the car all the way up for once and it starts doing this crap and gives zero codes......
anyone got an idea?
