here we go, the 2 wires of the iat were touching because i had 1 of those performance "chips" hooked up. i got tired of it so i took it off and had to resolder the 2 wires back on the iat (good thing i saved the plug) i guess after driving around in the bakersfield heat, the solder points melted just enough for the 2 ends to touch and put the car in "limp mode" so after the diagnostic test and reset, all that was needed was some rubber tape and embarrasment
