I've been having this code for a little bit now. I cleaned the MAF sensor which was the easiest thing to do and the code came back 30 miles later. I deleted it and it came back 130 miles later. I'm guessing its not a big problem since it takes so long to come up but I still dont want it to get worse. I took it to pepboys since they said they could get the problem, called me an hour later saying they couldn't contine checking the car cause it had aftermarket exhaust and aftermarket intake and the ls was very sensitive to aftermarket parts. They said I had to remove the aftermarket stuff so they could check it completly, yeah I'll swap them out right away for ya. So I gotta keep working at it now. I tried searching on this but not a lot comes up.I posted a while back and got this possible problems. Any other info is appreciated.Oh and they said running too rich meant its using more fuel than it should. But can it also be normal fuel and less air, normal air too much fuel?
