My 2003 GT seems to be idling a little rough, fluctuating between 600-800 rpms. Also during strong acceleration above 5000 rpms the check engine light will flash for a minute or so and then disappear. I have a cold air intake with K&N filter, underdrive pulleys, timing adjuster and MAC cat back exhaust. Could my MAF have the oil on it I've heard about and if so what is the best method to clean it.
TIA,
Brad
