I've recently been having a problem with my car idling VERY low upon starting it; this normally happens once I've already run it once or twice during the day (it doesn't do it first thing in the AM when I start it). I have to put my foot on the gas and run it up for a few minutes so the engine warms up. Once it's warm, there's no problems.
Any suggestions or thoughts on what this might be? I just found out that my front calipers need to be replaced, which is gonna cost me $500 or more, and I reaaaally hope this idling problem is a cheap thing to fix!! :(
