So i have a odd issue lately. I wasmessing around with some stuff and unplugged my mass air flow sensor. I forgot to plug it in and drove around for awhile. Truck drove fine. Then kicked on my check engine light. I drove around for a week or so then remembered I had it unplugged. So i plugged it in. Now my truck has no power down low. Takes forever to spool and is very unpredictable. So i replaced the sensor. Same problem. Now if I unplug it my truck drives great. Besides throwing codes. As soon as I plug it back in. Its a turd. Cant get outta its own way.. I'm lost. I've read every wrote up I could find and nobodys issue seems the same.. any help would be much appreciated!

Have you cleaned it with maf cleaner? The truck goes into default fueling with it unplugged

Do you have it installed the right way..... don't ask me how I know but it will limit fuel if it is backwards
