Leaving Skid Marks
Hoping someone can help:
Car starts and idles smoothly when cold, but when up to temp, is idling way to fast, 1500 to 2000rpm in neutral no A/C.
the idle is smooth not rough , i have cleaned ISC. cant wind idle down on throttle body, screw already at lowest setting.
check engine light is not on, but i have a fault code 13 logged at some point. (intake air temp circuit)
i will reset ECU and see if that fixes, but can someone firstly confirm the IAT sensor is part of the MAF assembly?
also does anyone have a test i can do for the IAT (ie resistance and which terminals on the MAF relate to the IAT? (Intake air Temp)
i know IAT is pin 2 on the ECU, but again not sure what the DC resistance should be.
i have openport 1.3 cable (+evoscan) on the way so i can log ECU and see what temp it thinks IAT is which may shed some light on the problem, but any advice or experience in the meantime would be appreciated.
The high idle may not even relate to the error 13, im open to any suggestions.
I initially thought a vacuum leak, but have pressure tested and cant find any.
