    CEL P0102 and P0113!

    I had cylinder 1 and 3 misfire codes on my 02 wrx. I had replaced the NKG R spark plugs with AutoLite double platinum plugs and the fuel filter and now my car does not want to stay on. The only way it stays on is if I repeatedly press the gas (Makes this weird popping noise every other time I press the gas and won't rev up more than 2800 RPM) and if I don't it will just stall out. I plugged the computer back in and got the P0102 Code (MAF/VAF Air Flow circuit low input) and P0113 (Intake Air Temperature circuit high input).The only mod on this car is an AEM cold air intake. Could someone please help with this.

    Make sure everything is plugged back in and fully seated... also make sure the MAF is clean, Also I'm just throwing this out there... Subarus are extremely touchy when it comes to certain aftermarket parts..Axles, thermostats, ALOT of ignition componants also, I have seen brand new coil packs and brand new plug wires cause dead misfires on Subarus before, just mentioning this, not saying its your problem... Have you tried clearing the memory?

    The intake is part of the problem. My guess is you have the MAF in backwards or it is borked.

    Well when I changed the spark plugs I did them one by one so I wouldn't get any of the wires mixed up. I only removed the window washer tank and my cold air intake but didn't disconnect the sensor. I didn't touch anything else. I had also noticed there was a vacuum line that was not connected. It was a little blue plastic T-shaped piece that was broken right under the intake manifold but I replaced that right away. Im hoping it is just a dirty MAF sensor. Everything was working just fine before I did the spark plug and fuel fulter change, just a little hesitation from clogged fuel injectors. I will try clearing the codes and cleaning the MAF sensor.
