Stalling & Electronic Throttle Control Light?
Hopefully someone can help me out with this problem so here's the whole story.
2006 SRT8 ( Aug '05 build ) with 54k miles completely stock. For about the last month the car has been randomly stalling with no warning lights either before or after the stall. The car would be running fine for about 10 minutes or so then at a light or stopped waiting to turn, the rpms would jump up, the car would lurch forward and then die. Restart the car and it would usually run fine.
I posted my problem to my local forum and was told to check the throttle body and clean it out, could be a sticking throttle plate. I checked it and sure enough there was a lot of gunk in there so I cleaned it out. Now its nice and shiny, looks like new. I did make the mistake of disconnecting the battery when I removed the throttle body. I was told this probably messed up the adaptive learning because when I put it all back together the idle was surging from 500 - 1500 rpms.
I reset the computer, pulled fuse #11 and did a throttle relearn. The car ran fine for a day. Yesterday 10 minutes into my drive, stopped waiting to turn left. The car jumped forward almost hitting the car in front of me and then stalled. This time all the dash warning lights came on and upon restart the ETC light was flashing. I immediately pulled into a parking lot and according to the manual cycled the key and the light went away. The car ran fine the rest of the way.
Today, left the house and at the exact same intersection approximately 10 minutes into the drive, the ETC light came on and was flashing, car went into limp mode. Pulled off, cycled the key, ran fine for another 35 minutes. On the way home, 10 minutes in, sitting at a light, rpms jump up and car stalls. No warning lights illuminate. Restart, another 10 minutes ETC light on and flashing. Pull over, cycle the key, ran fine another 30 minutes and I'm home.
I'm sorry for the long explanation, but hopefully someone has some ideas on whats going on. Like I said, 54k miles, out of warranty, completely stock. Thanks very much.
