It reads the air charge temperature and the eec makes changes to fueling based on it. I would assume carb cleaner would be okay to use on it. Might just have to buy a new one.
It's plugged in and she runs better. Now I'm getting a check engine light on right about the time when she gets to operating temp. what's the procedure for the engine on code test? I have a OBD1 code reader without the manual...LOL
This kinda seems like I have a problem with an O2. Just seems about the time when they'd be up to temp.
The code reader might have a PDF manual available online. Worth a looksie.
KOER codes are retrived about the same as KOEO except that the car is started (and already at operating temp) first.
You might find the CEL is from an EGR code if the light is coming on as you get up to temp (the O2's are functional way before you reach operating temps).
