I have a check engine light that just came on. I was using a (related nephew) napa mechanic that has been a little iffy for a while. Anyway, I didn't go to him with this because the car is running, right now. Is there an IAT on my 2002 Explorer? Codes P0102, P0113, P0171, P0174, P0300, P0316, P1130, P1131, P1150, P1151. Some may be old, I haven't or don't know if I should clear them. IAT is what the codes say. I changed the MAF sensor and the truck ran like crap. Put the old one back on & returned to Auto Zone. I passed inspection last year for plates (2015) after an O2 sensor change, not needed for new ones this years (2016). So car is running, but for how long? So, should I change IAT (if I could find it) or what? Please give an old guy(65) some help.
Thanks, Tom

If I were you I would clear the codes and see what if any comes back. That will give us a better chance to narrow down your problem.

Hi Car-man145, It took a couple days waiting for scanner to get here. Anyway after resetting trouble codes and running a new scan, it might be a little easier for you guys to diagnose. the new codes came back.
Stored: P1131
P1151
Pending :P0171
P0174
Hope that'll help you to help me!

Thanks, Tom

I also got some MAF cleaner and sprayed the heck out of MAF sensor.

Sound like you have a vacuum leak check the pcv valve hose for a leak but you need to find the leak maybe the intake but a lot of vacuum lines to check first.
