so was the wire pulling on the MAF plug when the motor would move, was a wire pulled out?!?

Wouldn't the car run like SHIT without the MAF?

I had a very similar issue with my 2005 GTO years ago. Turned out to be a bad wire in my MAF harness. Replaced the wire, CEL was gone. It ran fine with the CEL, a bad wire or a pulled/loose wire will not necessarily be noticeable as far as drivability is concerned.

well, it's cleared itself, and came back. Dealer is going to look at it on Thursday and they think that I have an exhaust leak.

I'll report back... waiting to re-install the RF until I'm done with the dealer.

I throw the same code after installing the filter. Throw it every couple 100 miles. StephenZl1 thinks its a bad 02 sensor. My code did start coming on after I installed the intake. If the dealer finds a solution would you please let me know the outcome? That'd be really appreciated. Thanks!

the ZLE has been back into service and they replaced Bank2 (pass) rear 02 sensor and checked the exhaust for leaks. The service manager is cool and told me to leave the RotoFab off to see if that's the issue again.

so far no codes, but it does seem logically to follow the RF and clear after I installed the stock intake and drive for 10 miles, I really prefer the way the RF sounds though.

I will say that the car feels more responsive at low RPM's putting around town, with the stock AF but you can barely hear the SC.

So, I'm either going to leave it off till I tune the car (March) or reach out to RF and see what they say.
