I have a 2000 Camaro 3.8L.*

The other day I got on it a little more than I should have. Nothing crazy though. The very moment after that, she started riding rough, and when I get to 3rd gear, the check engine light comes on.*

I ran a scan and pulled P0113
(Intake Air Temp. Circuit High Input) and P0305 (Misfire cylinder 5)

I just changed the IAT sensor, took it for a test drive, and it threw the same code, and still runs rough. Light still comes on when I get to 3rd gear.*

I am at a loss, is there something I am missing, and is there something specific to this model year.*

Does anyone have any ideas?

I already moved your original post, with my responses to "67-02 General F-Body Tech", where I felt you would be more likely to get additional input.

No need for additional posts. It just causes confusion and duplicate efforts by the people trying to help.
