I have cleaned the ICV with WD-40 etc and it did not help. And when I pull the power plug off ICV while the car is running, the idle does shoot up to 2000 RPM.

Is there any way I could test the TPS? Is the middle tip the ground so I could just follow the V change to see the TPS is bad or not?

I will do both the AC and CSI tests this weekend and I will report back my findings.
