Hi,
If the check engine light is blinking, that indicates at least one cylinder is misfiring.
As far as the MAF, have you replaced it? The MAF incorporates the IAT (intake air temperature sensor). Also, have you checked the air intake tube where it mounts to the throttle body? There were issues with them cracking and allowing unmetered air to enter the engine. See pic 1 below.
Next, if you sprayed a lot of throttle body cleaner into it, that could have caused issues for the spark plugs. Also, when you open the throttle plate by hand, you have to perform an idle relearn procedure.
Do me a favor, take a look through the manuals directions for cleaning the throttle body. (See pic 2 below). Pay attention to what I highlighted and check the product you used.
If you look at pic 3, it explains the idle relearn procedure.
The last recommendation I have is to remove the spark plugs and make sure they are good. If you sprayed a lot of throttle body cleaner into the throttle body, the plugs could be fouled or have dirt on them preventing spark.
