On my 5.0 I have a steeda CAI and dyno tune, I'm calling my tuner tomorrow but just now I did a 2nd gear pull to red line (no rev limiter) and let off the throttle then took it out of gear and let it coast. Then I saw the wrench light, my throttle was gone, no power, and it stayed like that until I turned the car off and then on again. After I turned the car back on the light was off I revved it up to 6k, just a rev didnt hold it, but no light came on. Car ran perfectly normal from then. Anyone know what could have done this?
