It is starting to get HOT!!! here in Nor Cal and I need my A/C .. but when I use it my idle goes nuts!! It feels like it is going to die but never does .. yet. Anyone know why this happens? or what I could do to fix it? I looked at my Power FC on the sensor check screen and the with the A/C on and the fan set to (1) it shows the sensor on .. at (2) it shows the sensor worker but at (3) it shows the sensor off and at (4) back on again .. WTF??!!! If anyone can help me out it would be appreciated.. Thanks in Advance
