man wtf wrong with my car now?

k, here is the deal........


I was merging on the fwy, not mashing out, but simply merging and the car all of a sudden had no real power, the car went smoothly, but no power. When I came to a stop I expected the car to shake, but it didnt. No, check light. I turned off my car and the car ran fine, whats going on with it?

Does yours have a SC? If your running smoothly, but with no power, maybe it bit the dust or something.

don't worry

Something similar happened to me. I accidently shifted to 6th instead of 4th. When I tried to accelerate moments later... no power. Seems it didn't like being "lugged" like that. It has not happened since.
If you turned off the ignition and restarted it and have not experienced loss of power again, then don't worry too much. (Crossing yor fingers might help too.)

The car likely went into limp home mode. Restarting reboots the ECU, TCU etc. Sticking the car into reverse while moving forward can trigger this. Obviously not the case here.

Could well be a one off event. Check all fluid levels including auto if it's auto & just watch it for a while. I've had this happen once 30,000 Kms ago never to return.

Coil pack? Thats a pretty good description of what happens when they're on the way out. Turning the engine on and off resets it,
for a while till it's a solid failure.
Whats the CEL code? If it's a misfire, swap the coil packs between cylinders and see if it goes with the CP.

Or...it could be much worse...people seem to have bad problems with that M271 engine. Valves and such.

Check MAP sensor, it's cheap to buy 1 just to check. After swapping for a new one, you must reset the car or it won't recognyze the new sensor
