It idles low then it kicks up then down etc... it does this over and over again until I take off. I have a 96 gl with 120,000 miles. Thank You.

It could be your IAC (idle air control) valve. I would never trouble shoot an A/C/Idle problem as it's expensive to guess and throw parts at it. Not to mention wasting refridgerants. 1996 2.5LT V6 Contour ATX My Tour+help/info pics E0 rims, Gutted Pre-Cats,CTA Custom Exhaust & Intake, Diablo Chip.

Charge it up and it should go away but you may need to fix a leaky component also. I live in Detroit, I couldn't give a **** how good my car is in the "twisties."

I had my system recharged like a few CEGers said and it didnt fix it, it still idles up and down just not as often for some reason, also there is no leak they used the dye no leak was present.
