Idling Advice?

My idle, of course, is at 750 rpms at idle. If i tap the gas it will miss and then pick up soon but still a small miss. New plugs and stuff. But if u tap the gas anywehre over 1100 rpms it wont do it. I'm not having any power problems what so ever. Also it sounds like maybe a vacuum house off under the hood but i was thinking maybe its the alternator. COuld i get soem advice maybe?

nah it doesnt sound like the altenator, it sounds like the car is running alittle lean (not enough gas in the air/fuel mix) try running 92 octane gas if you dont already and see if that helps. another thing is you could try is to adjust your idle so that its jsut alittl higher. The only way to richen the mixture out is to do it electronically since the air/fuel curve is computerized throught ECU. If you really worried about you might want to look into a S-AFC. this is a decive that you install that will change the air/fuel ratio that your ecu reads. BUt these are in the $200 range....for a used one. I had one but sold it. anyways..hope this helps you.
