Hey guys as many of you know i had Dan M build me a truck a couple years ago. 6 months ago i had a diesel shop put the 3200 rpm governor spring and fuel pin in it to give it a little more power (although it doesn't hit anything close to 3200 RPM) anyway in the last couple of weeks its started running 220 instead of 180 like it usually does) and and when i pull over its idling much higher. The coolant is overflowing out the drain hose. Ive driven it for two years an never had this problem. Ive topped of the fluid but still its running warm. the only thing I've done to it right before it started doing this was put a new air cleaner on it because the old dirty one was obstructing air. Could the fuel mixture be to lean now or what could be making it run warm and idle high?
