What the heck is going on?

Ok guys I have a problem when I turn on my air conditioner my idle goes for normal to horrible but as soon as I turn of the ac the idle goes back to normal. I just changed the crankshaft position and the icm ( ignition control module) boots, coil pack, spark plugs, and fuel filter. It was stalling but not anymore since I replaced the Crankshaft Postion Sensor so its not doing that anymore. I need your help guys!!

i looked it up with the gm tis2web website you enter your vin and it tells you if you have any new updates. when i got my tune from vince for the turbo install i got all the gm updates available (he buys the most updated tunes from gm then modifys them)

me too. and yeah basically print it off the net go to the service counter and tell them there are some updates and without it it is causing your car to stumble really bad and sometimes stall because of it. they will probably do it under warranty then but my old dealership sucked and only covered my emblem seperating before i drove it off the lot.

Sounds kinda normal to me. Mine bogs down some when I turn on my AC. It's because your loading the engine down and not bliping the throttle. PCM Probably does that to some extent though. How bad is it? Its noticable on my car, but I wouldnt call it a bad idle.

You mean GM didn't notice this when they first produced these cars and program the PCMs accordingly back in 2004, when the 2005 'Balt was in devolopment???

No you dont go in and ask... you strut in there like Travis Trit high on Viagra and demand that they update your ECM and you tell the Service Manager that while your waiting you will be screwing his mom..If that doesnt work..then add (Please) on the end of it...

Give it a try!!!!...

Cels

My engine check light is on but I dont know what they are since I dont have a scanner. Sorry but I wasnt clear in my post guys sorry. Its when I am braking and the ac is on the rpm usually dives in 600 rpm which is understandable since I am braking but here is the thing when the ac is on it dives into 400 and 300 and thats when it gets bad because the car feels like it wants to stall but again it doesnt. If you guys are having issues where your car stumbles on acceleration you might want to check your coilpack and all that hardware or cps as well. I changed all of that and it doesnt stumble anymore. I am just having problems with this ac thing I am just thinking about driving with my ac off or maybe even stripping it that way my car is lighter lol.
