What made me think mass air flow sensor was that when it is unplugged it fixes the problem. No more limp mode. However now my ECU will not connect with any type of scanner tool.. I had the same guy at autozone do it for me and I did it myself and neither of us could get it to work any longer. Its most likely not the wiring harness because it doesn't happen from bumps. Either way I cannot scan my codes now so I need to figure out what is wrong..
