Hey guys I'm new to the forum and was wondering if you guys could give me some more information on how to fix these check engine light codes that my 1998 Grand Prix GT 3.8L N/A is throwing. I went to AutoZone and they let me use their OBD-II scan tool and I got 3 codes that showed up when the scanning was complete.
The first code is: P0108 and says on the paper that the MAP (Man. Absolute Pressure), BARO/MAF (Mass Air Flow), or VAF (Vane Air Flow) sensor(s) are bad.
The second code is: P0507 and says on the paper that the IAC circuit condition or idle speed is higher/lower than expected.
The third code is: P0113 and says on the paper that the IAT circuit or sensor is bad.
I know that most of these are just minor problems and simple fixes that involve putting on new sensors on certain parts of the car. I recently installed a short ram intake on my car, so could that be the reason why the IAT sensor is bad? But my question is where are all of these sensors located on my car and how do I go about fixing them? Are these codes saying that it is more than changing the sensors? Any help is appreciated. Thanks in advance.
