That indicates a problem with the data coming from Mass air flow sensor or it's circuit.

If you're running a K&N filter, get a can of MAF sensor cleaner & hope you didn't kill you MAF.
Where can I find it at, (MAF sensor cleaner) call all part store, no luck!!!!
They may have it & not realize it.

It will be in the carb cleaner, throttle body cleaner section. I believe Gumout (sp) makes it. The one I use is in a gray can. It's designed specifically for MAF sensors, not as harsh as carb clean & does a good job. The main area to clean is the little sensing wire inside the housing

I stand corrected.....it's CRC
