My car at idle when i first start it up is good a little rougher than before but my main problem is when im driving with the AC on the car feels very laggy compared to when i dont have the AC on. When shifting the car loses a bunch of rpms and gets to the point it bogs a little. At stop lights the idle goes as low as 700 then adjust to about 850 to 900. I dont have a problem without the AC on it feels just fine. Also it feels like crap when i first drive the car even without the AC on untill it warms up and i usually let the car sit for a minute or two just idling. I know this is long but if any of you can help i would appreciate it. I think my problem is caused by a bad ISV valve from what i have read on here. Thanks for any help

 

they're cold blooded.

fw wilk had some comments/fix for the rpm dropping then recovering but i'm not sure his site is up.
