2005 Ford Taurus-Starting Problems
I have a 2005 Ford Taurus 6 cyl. The past few months the car has had intermittant starting problems. The engine cranks over just fine but will not start up. Doesn't matter if it's hot, warm, or cold. I hooked it up to a scan tool and got the PO300 code which is interrmitant misfire code. The car has not really run bad after starting. Through the options of possibilities I replaced the coil pack and the car has started just fine the past few weeks. 2 days ago the starting problem has returned. I hooked the scan tool back up and it shows no codes. I can unhook a plug wire, ground it with a screwdriver to check for spark and the engine will fire right up. Any ideas what to check for ?
