M20 ECU Coolant sensor weird idle.

04-09-2012, 08:10 PM

My car idles low when cold and high when hot. I was curious if the coolant temp sensor could cause this. My multi meter is missing to check the ohm load. Anyone have any ideas?
I have had the car smoke checked and fixed the bitch tube o-rings.

Hard to tell without a multimeter. IT could be something else like the FPR.

The FPR is new and vacuum line fresh
