My CEL came on after I cleaned my MAF Sensor and sprayed cleaner in the throttle body. Probably because I had everything taken apart as I ran the engine when I was spraying the cleaner. Anyway, how many cycles does it take for the CEL to go off on it own?

got to an autozone or some such that will check CEL for free. See what it is. Turn it off.

Advance or AutoZone should be able to clear it for you. Alternately, if you know someone with an UltraGauge, ScanGauge, or similar product they can clear it for you. It won't come back on after that unless there is a legitimate issue.
Ended up taking it to AZ. Codes are P0171 and P0174....running too lean on both banks. Hope I didn't damage the MAF sensor. Apparently AZ will only check the codes, they won't reset them. I'll do that tonight with the battery cable.

If you used MAF cleaner and allowed it to dry before putting it back, it's highly unlikely you damaged the sensor. If you did, however, it's a fairly cheap fix if you do it yourself. e.g. Amazon sells a Hitachi MAF for the 2011 Expy for $50 shipped.
