Check engine light help

WRobX · 12-29-2005, 08:01 PM

Last night my check engine light came on during a drive home. I turned off the car, started it up, and it didn't come back on. Today, the same exact thing happened. I've only had my car for a few weeks and haven't had time to install any of the new parts yet. I did, however, throw a K&N panel filter in two nights ago. I can't see how that could trigger anything, but thought I would mention it. Any thoughts?

...too much oil on the filter coats the MAF and makes it throw a code.....also, if ya didn't get the airbox top back on right---it is a PITA sometimes to get back on.....THAT can cause a CEL....or your gas cap could be loose......or....

...without the exact code, as in "Pxxxx" we are pissing in the wind.

...and the stock paper filter is better than that K&N junk

Why do you say that the stock filter is better than the K&N? very curious here. Thanks for the thought on the airbox. I'll check it out in the morning.

Ya loose power with the k&n over the stock filter.

Proof....dyno proven proof. It has been posted here...back to back dyno runs.....and don't forget, they don't filter as well, either.

The stock airbox, filter included, is actually pretty good.

I checked it out again today. The filter didn't seem to be seated properly, so I took off the MAF hose to get a better seat. We'll see what happens.

UncleScotty-do you happen to have a link to these charts? I'm not trying to be confrontational, again, I'm just curious.

Thanks for the input guys
