I ran my 07 3.6l cts in our local track hit a best time of 15.004 @93 mph 2.0 60' spinning a little at 90 degree weather. As soon as I ran I shut off the car 30 min later started her up for another run and had a rough idle and check engine turned on. Ran a test and turns out to be the mass aur flow sensor. It has a rough idle at cold start only but is perfectly fine driving. Can it be that the sensor is just dirty?. Posted the time I ran just incase anyone was wondering lol.

My mpg has taken a bit of a hit as of late. I've been contemplating a new MAF (instead of just cleaning the one I have...what the heck it's about 7 years old and I don't feel too confident about just cleaning it, everything has a life limit anyways) , cleaning my filter's intake and cleaning the throttle body.

Sometimes replacing the MAF with a new one is the way to go.... sometimes
