Problems - Need Help

[mikeisgod]

Hey guys this is Mike... I have hopefully an easy question for some technically savvy people... Within the past two weeks my car is acting up. It seems like it is cutting out... either not getting fuel, or something... It seems to instantly start happening when I turn on the AC, if I turn it off it calms down but still acts up. If I leave the AC alone for the "most" part it does alright, though sometimes it does act up a little bit still. At Idle when i'm holding the brake is the worst... Anyone have any ideas? My friend told me it could be a vacuum leak.... Has anyone heard of spraying carbuerator cleaner on vacuum hoses to check for a leak? Apparently if the engine starts revving, there's a leak...

Thanks,
~Mike

All of this is at idle? What is it doing when cruising down the road?

It does it at idle worst. But it does it while cuising also. Haven't tested it above 50mph though... but it does it up to 50mph.

The carb cleaner trick will work for finding vacuum leaks, but your throttle body might need a new Idle Air Control, it is a motor that lets some air bypass the throttle plate (mostly at idle) and it has a role in controlling idle speed. It could be effecting your cruising slightly like you say.
