When the A/C its turned on.....
My rpm's drop low, and when I turn it off they jump up for a second and then start to idel normally. Some say this is normal, any opinions?
Thanks for any info ahead of time!!

Sounds like it's the A/C compressor cycling...how many rpm does it drop? 200-400? If so, that's normal.

It's in the owner's manual, if you have one. You'll need to unplug the battery to clear the adaptive memory, or if you have a tuner re-flashing the tune will clear it. Then let the engine warm up to operating temperature and let it idle. The manual says for a couple of minutes with the A/C off, I usually let it idle for 10 minutes, then turn the A/C on and let it idle again. Then the computer should hold the same rpm's whether the A/C is on or off, unless you have some other problem.

My 05 was doing that too.
There is a slight drop (which is normal)...and I mean slight.
I had it to a point where I thought it was going to borderline stall.
Throttle body ever been cleaned?
