Rubber Side Down
I don't generally warm up my car by letting is sit and idle, but it was about 1°F this morning and I have a very short drive to work so I let it run for about 10 minutes. When my daughter and I got in my car it wreaked horribly of burning rubber and it was pouring smoke out of the exhaust. The temp gauge read normal, but it was still idling at 1500 rpms. I blipped the throttle and the revs immediately dropped to normal warm engine speed. I am due for oil and a filter (10,000 miles), but I'm not sure that would have anything to do with it. Any insight?
