That's because it's going through a readiness test during that 40 miles or so. Some cars take 80 miles to get there, some take 20. It means the problem's not fixed. Bummer, huh? Anyway, luckily multimeter's are cheap, so that won't be a big deal to test the MAF sensor. Good luck, and I'm stoked to hear that the car was not smoking out the filler neck.

Ok, since you didn't answer my question. I checked your profile. You're running a K&N Typhoon Intake. Does it have the heat sheild and are you tuned for it?

Sry.
Yeah I got the heat shield and no its not tuned for it but I installed it a while back and never had any probs with it.??

So today I unplugged the MAF sensor while the car was running and surprisingly it stayed running it actually sounded a lil better while ideling Ive read if it runs better with it unplugged that its def. the MAF because your using a different fuel map. So my guess is going to remain the bad MAF sensor. I was gonna try the multimeter test but didnt want to risk breaking something else.

So Im gonna pick up a sensor this weekend and Ill post the results.

I have heard someone talking about the same code with the k&n intake...they put a cobb intake on the car and it seemed to solve the problem...and cleaning the maf sensor and putting it back in did you reset the ecu? because these cars have something like corrective learning, so while the car is figuring out the maf again it may not throw up any cel's...

Well, if the MAF theory strikes out. I'd try to get a tune for the intake or get rid of it. The 02-07s really hate the intakes to be switched out without a tune. The 3rd gens can't really run anything either without a tune. But, some of the intakes can be tuned for with OS maps made for them. So, do the homework accordingly.

@Baum
I reset the ECU after cleaning it and got CEL again after 40miles.


@Turmic
Yeah I was gonna try to get a tune after I get a DP. I wasn't sure you needed a tune for a intake though I guess what ever mods you do to your engine should get a tune.
Im still learning

I had a 06 that I swapped the intake on it and lost a massive amount of power so ended up putting stock box back on.

Didnt seem to lose any power when I put the K&N on this one though.

Thanks for the pointers Turmic

Well picked up the new MAF and installed it and runs like a champ again!
The guy at AZ said that intakes w the oil cones are known for ruining MAF sensors.
Think its about time to invest in a SPT intake.

The SPT intakes are restrictive as well... FYI
