I figured I would post this up in the event that anyone experiences it and they turn up this post in a search.
Yesterday, while driving my car abruptly lost power. A message Eng Pwr Reduced
blinked on the console and the car started dinging. Then the engine cut out and Engine Disabled
At first all I did was disconnect and reconnect my battery, and it worked. But then, the same thing happened about 20 minutes later. This time, the check engine light came on. My first instinct was to take it to autozone and have them check the engine with their code checker.
Then, just because I was curious, I opened up the gas cap door, and sure enough, my gas cap was wobbling loose on the filler neck. A quick tighten and the problem is now gone.
This is just a warning to anyone who has this issue, that your gas cap may have been screwed on incorrectly by some incompetant gas pump attendant.
Damn New Jersey and their Full Service laws...
