Restricted performance message

Most of the time when a random misfire codes if the MAF doesn't fix it it will be a weak fuel pump or the engine needs new spark plugs.

Here is a guide to help you see what you are in for when changing the spark plugs

I would also service the throttle body

Also scan the PCM for codes.

Please run some tests and get back to us.
