Lack of power

You need a simple code reader.
You then do not have to disconnect battery to reset.
At this point you don't know what the code was so you can't target your repair.
Hunting idle can be due to dirty Throttle body/Intake (My issue - didn't throw code nor was power down)
I have also read that disconnecting the MAF is a diagnostic test. You should be able to hear it in the idle if it is hunting

just regular ODB2? I guess I will drive around with a hope that the engine light will come back

Yes you can drive around for a short while with the MAF disconnected to see if that's where the problem originates.

I would use only MAF cleaner and spray the MAF and the plug and hardness connectors and give it 10 minutes to dry before reinstalling.

Also pull your air filter and inspect, clean or replace it.

With the filter out, inspect the inside of the airbox for foreign objects and make sure its meticulously clean in there.

If possible by mirrors, inspection cam or camera, look in the airbox down the intake pipe towards the MAF to see if anything is stuck up against the screen that is upstream of the MAF as disrupted airflow can also make your MAF crazy.

It should be operating room clean in there for the MAF to do its job properly.


My MAF was acting crazy and I found a part number sticker in pieces in the airbox under the filter. I cleaned it all out and sprayed the MAF and connector which caused all the issues to go away. (Wandering idle, engine light for MAF and other codes etc)
