Hi All,<p>Yesterday I got into my R after it sat for 3 days to receive an error upon starting the car stating that the car had "Reduced Engine Performance".<br>I drove about a mile not feeling any difference in performance and stopped to fill the car with gas. When I restarted it the message was gone. This happened again this morning when I first started the car and again it went away when I stopped and restarted it. Once again, no apparent loss of power. I currently have 53,000 miles on the car and for the most part it's been trouble free.<p>The only thing I did the other day was check the air filter to see if it was filthy as we've had a ton of pollen here lately. I banged if off in my hand and put it back in. It was really clean to start with. The car it totally stock.<p>I searched the forum, but only found examples of limp home mode, nothing that involved the error, but no power loss. Any help is appreciated.<p>Thanks,<p>Ken

Make sure your clamps are tight and all the hoses connected and not torn.<p>Kind of strange you didn't feel any performance difference. "Reduced engine performance" IS the limp home mode(for the engine) which usually results in reduced engine output(way less ponies).
