Cleaned MAF sensor incorrectly awhile back, car started idling rough but once I got driving it'd be fine and level out, I finally replaced the MAF sensor with a duralast sensor from Autozone because my check engine light started flashing. now the car idles extremely rough doesnt fix it self and stalls if I leave it still to long. I have a very simple after market CAI on the car that DIDNOT need a tune when installed. any advice would be great.
My car has 92000 miles.
My car has an automatic transmission.

Occasionally, on a part of this type there are meaningful differences between aftermarket and OEM. Therefore, to simplify the diagnostics, the OEM MAF sensor (as vended by a Ford dealer) could be installed. Once you have an original equipment, genuine MAF installed, and thus have ruled that component out as a cause of the engine performance problem, OBD-II codes are read (if codes are still present), with freeze frame data, and the components identified in those codes are tested in turn. That testing is described in the "diagnostic decision tree" in the factory manual...quite a few steps to go through. Once all codes are resolved, if the problem persists, a rough idle diagnostic would then be performed and that, for sure, will resolve the issue.
