Moxie, THis line where you meant A/C ON I assume..... I would think this is "hanging" just a little to high...but no bad (as VMF has said) This would bug me too ;) I know my old honda 4 cyl.. would boost the idle just a touch with the AC on, but the beefy LS V8 doesn't seem to budge. This does not happen on my 99 LS. I'll be more observant as I drive today and report back :D (Air Filter Dirty????) 99 Oops my bad on that one. Thanks for all the replies... if this is just the way it is I'm kinda bothered. :/ Thanks for checking, and thanks as well VMF P.S. Airfilter has been in for about 4days, just replaced. This problem has been evident ever since I got the car about 2 years ago, it has just started to irritate me.

Thanks for all of the replies folks. I was doing some research last night when the car was warm, and I was wondering if you could provided some insight for me. Once the car is warm the idle drops like everyone said, but the car idles too high with the A/C on and the transmission in gear. Idle Speeds Park A/C Off - 650 +-50 Park A/C On - 650 +-50 Neutral A/C Off - 650 +-50 Neutral A/C On - 650 +-50 L, 1, 2, 3, D, R A/C Off - 650 +-50 L, 1, 2, 3, D, R A/C Off - 900-1000 The problem isnt horrible, but sitting a stoplight you have to apply the brakes pretty hard when the engine is pushing close to 1000rpm. Any help here? And thanks again for all the help :)

Thanks for the quick reply. Once warm the idle is around 700 or so. How long does it take for yours to resume normal idle? I'll run some more detailed tests over the course of the week, anything else specific I should look for? Also, is there a way to adjust the idle, or check codes other than a handheld tester?

Greetings, Well after searching for 45 minutes I didnt find what I needed so I hope someone can help. Our 95 LS400 idles pretty high on cold days (less than 95 in Phoenix lol) It is usually around 1400 rpm with the car in automatic climate control. Once its warmed up the problem goes away, and like I mentioned on 95+ days it seems fine from the get go. The engine hasnt tripped a code or thrown a CEL. I appreciate any help you can offer.
