Just got back from a Sunday cruise and I am getting a check engine - P1111 and P0113. Check engine only came on after I pulled in the driveway after an hour drive on my 99...
I just got the car back yesterday from the shop where they installed a new SLP Blackwing, C5 Z06 exhaust, wheels/tires, and oil pressure sender.
P0113 is your AIT sensor. My guess is that you new intake install is causing the code. Did the mechanics move the AIT from the factory location or not connected it appropriately? Also, after you restarted the code was it Active or History?

I just took the system apart and cleaned the MAF since I had the cleaner. MAF and IAF connectors reseated.
Attaching some pics of current setup.
Car was fine all day yesterday and this AM - CEL only appeared when I pulled into the drive way.
After the MAF cleaner, I reset the codes, took a short drive and no CEL. I also emailed the shop to get their thoughts. I am thinking that the Blackwing was over oiled from the factory, and it sprayed all over the system. Stay tuned!
I believe the 0113 is a IAT signal circuit "high' which means the 5 volt signal wire (tan wire) isn't getting pulled to ground through the sensor and the ground is being supplied by the purple wire...with key on see if you have 5 volts at the tan signal wire first...if good now connect a 12 volt test light to battery positive...probe the purple wire and see if the test light illuminates which indicates you have a good ground...the ground is a PCM ground.
From post #4 the picture shows what could be a crack in the air bridge bellows just before the throttle body. Check that- it could be un metered air coming in.
