I have the Fujita CAI and have thrown a CEL 3 times. Once, after I first put it on. I popped the negative battery cable and all was well. The second time, the CEL was on for a couple hundred miles and then went away, and then the third time was just a couple days ago. Is my car actually running lean or is my MAF just thinking it is? Can I damage my engine by ignoring the CEL and continually driving it? I throw 4 codes. P0171 and P0174, and then the same codes with a PD behind them only the P and D are small letters and are diagonal from one another. What do these PD codes stand for?
I took the CAI off the first time and totally reinstalled it so I doubt I have a vacuum leak. I think my MAF is just acting up.
