Check engine light after tune
Two weeks ago, I purchased and installed the SCT Tuner and AirRaid CAI from American Muscle. I installed the Performance tune, and everything seemed to be working OK for about 15 miles or so.
I kept it garaged during the winter (yes, I properly winterized it), so decided that since the temp was about 40F, I would take it to the quarter car wash to give it a thorough cleaning.
After about 4 miles, the Check Engine light went on. Mind you, the car still seems to perform well, but I'm wondering if the tune I received might be missing something. I checked all of the hoses, and made sure I didn't miss anything during the installation, and the tune completed without error.
I'm planning to take it back to stock tune to see if the issue goes away. A couple other questions include:
Can I use the SCT tuner to determine why the light is on?
If it is running well, should I continue to drive it?
If I take it back to stock, and the light stays on after another 15-20 miles, should I take it to the dealer, and is he going to ask me to remove the AirRaid CAI?
Your suggestions are greatly appreciated!
