not sure of any vacuum leaks. and no check engine light. took it to ford about 1 1/2 years ago. they changed a harness that pluges into the module that supplys all 4 spark plugs. 280.00 and it still wasn't fixed. I do understand intermittent problems are the hardest to find. thak you i'll check and clean both of those.
