Engine has recently begun fluctuating its idle, when the engine is cool the idle stays just below the 1 on the RPM guage, as the engine becomes hot when in the lower gears the idle either revs up to 2 on the RPM guage and hangs or returns back to the below 1. It can get stuck in the high idle or it will rise and fall randomly.
Attempts to resolve include:
replaced the spark plugs with correct manufacturers recommended brand
Replaced the oil with manufacturers recommended 5W-30
replaced oil filter
replaced fuel filter
removed part that comes off the air filter and cleaned it with carberator cleaner as recommended let it dry over night before reassembly
I regularly check oil and coolent levels
what exactly am I missing that will resolve this issue?
have the same problem?
