Idling Problem

October 19, 2006 11:36pm CST
When idling after engine is up to temp., the idle speed fluctuates, goes down to about 500rpm and then up to 1500rpm then settles down to normal about 900rpm, more noticeable after a bit of a long run.This does not happen all the time, also when accelerating there seems like a sudden power surge, it's is like a boost has been actuated,with a slight surge in speed
