Are all of the sensors screwed in completely? Is the temp gauge going up to H immediately or after it warms up? If it is immediate, something is wrong with the switch. If it is after it warms up, it's probably overheating. The fast idle screw should be screwed in and then backed off a turn.
thanks for your input, when i figure out whats wrong with it i will let you know for future refrence in case someone else may have this problem.
