Hey Guys/Gals, trying to get some ideas of what to go after on my Son's 06 SRT8 that stalled in traffic yesterday, then after it restarted, accelerated while his foot was on the brake. I know it has a linear gas pedal connected to the PCM I believe. He said he tried to pull up any codes on his dash display but none came up. He said the oil light came on when it died which is probly because the engine died. Said all the fluids are good. He's headed home from college tomorrow, bout a 4 hour ride and would like to have a game plan to fix it when he gets home. I've seen some threads when I googled shut down problems which pointed to defective pcm's...but also usually no codes set. Acted like pcm didn't know where the gas pedal was at, and started running a position check on it? stabbing in the dark here. Car has an aftermarket remote start that will start the car 2x's after you reconnect the battery? I plan to get this taken out by dealer that installed it as I think it might be interfering with the tire press monitor system, and it could be causing this latest issue too. mI appreciate any help on this.

It's likely that the shut down and restart caused a glitch in the TCM/PCM interface. I would disconnect the battery for a few minutes and then reconnect to reboot the entire system. Then see if it happens again. I would also check the battery and make sure it has a full charge.

You can also pull fuse number 11 under the hood for 1 minute to clear codes and reset the TCM.

A temporary fix for the stall after refueling that sometimes works is to leave the gas cap off for about a minute after you put the gas nozzle back on the pump after filling filling up. Then put the gas cap on like normal before starting the car.

Thank you JTW! Holy Cow...what a long thread, but worth the read....its extended warrantee, not a TSB that gets it done. Gotta call Dodge again tomorrow to see if the car is covered...its an 06, but not sure if its in the window date-wise. The ntsb said 05-06's covered, but leave it to Dodge to cut the list down

Your '06 SRT should be covered. Mine is.

The sudden over reving in gear is a result of a faulty PCM/TCM response. You need to first fully reset the entire system and then proceed from there.

The system has interlocking programming that should prevent that type of behavior but it can result from glitches just like your home PC can. First thing is to reboot and then see if the issue persists. After that, start logging and chasing codes on a clean slate so that you can get an idea of what is going on.

Your PCM may be fragging itself, but until you reboot it...you can't know what it's actually doing.
