What the hell is happening? I have no engine mods, except a K&N filter which has been there since I bought the truck in 03. Last year was the first time it did it, I just unhooked the batt. and the comp reset I guess. Then, yesterday, I was on a drive and all three came on at the same time. Anyone heard of this?

 

All three you say? hmmmm.......Sounds like your truck will explode soon.

 

Sounds like it threw a code. The service dept. can hook it up and locate the problem.

 

well, decided to unplug the batt. again, lights havent come back on in a couple of weeks. So far so good. Thanks for the replies.

 

Did you clean your K&N filter shortly before the codes? K&N filters almost always have too much oil on them when they are new, and sometimes have too much oil put on them when they are cleaned. Long story short, the oil gets sucked onto the MAF, and starts causing problems. You can get some electronics cleaner to spray the MAF down with. Next time it throws a code, AutoZone and a few others will scan it for free to see what code is being thrown.

 

No, I havent cleaned it in a couple of months, which I guess I should probably check that too pretty soon. Thanks for the info about AutoZone though, thatll be great for future reference.
