Default rough idle when using a/c

It doesn't do it all the time but using the a/c seems to make it act up more. Idle's rough but seems to run fine. Just started doing this the last couple of days. When i come to a stop is when it is most noticable. When i turn the a/c off it still will idle rough and then it just magicaly fixes itsself. Checked all the vacume hoses and cleaned the air filter.

Check the Plugs, wires and coils as well... Those can cause the problem you have described too.

It sounds like your car just needs some more idle tuning. Some tables in LS1Edit actually have two different rows of values, one for AC on and one for AC off. The AC on values might just need a little tweaking.
