Q: Rough idling when cold, would not idle when it warms up
My vehicle has idling problems. When it is cold, my car would idle roughly. It wouldn't idle at all when the vehicle warms up. It has around 200,000 miles on it. I had fuel filter and fuel pump replaced. Also, the iar filter, spark plugs and wires were changed along with MAF, PCV, IAC and MAP. The car runs well at higher speeds. I don't know what the problem is. Please give me some advice.
