1st, is the check engine light on?...How many miles on he vehicle? I would suspect the throttle position sensor (TPS) . Also, the mass air flow sensor (MAS)....Or,it could be you just need new spark plugs and, or, wires....

Cleaning the throttle body is certainly the right thing to try first. Make sure you clean the throttle plate as well.

Idle drops when in park

You should check with a scanner to retrive the codes the PCM register,depending the code you can either send the vehicule to a mecanic or to a GM dealer for repair.Do not desconnect the battery anymore or you'll loose all the PCM codes and it will be difficult to find the exact problem.luck!

Classic signs of idle air control not able to cope with sudden engine loads. Cleaning should resolve this. Remove ducting from air cleaner to throttle entrance. Spray with carb. choke cleaner or WD40 spray and wipe back to the alloy finish. clean the the throttle plate and push the throttle open with your fingers and clean in behind as best you can. Clean the passageways to the idle air control valve. Remove the valve and give it a thorough clean up. Reassemble and it should all be good.
