If anyone can help with this it would be greatly appreciated. I have a 1998 Explorer with the 4.0 SOHC and about 98K miles. Everything was fine when I left it for about two weeks in the driveway. When I came back the MIL was on, running rough and a moderate to loud ticking noise. It was a great massage on the way to hockey practice. When I returned I read codes P0304, P0305 and P0306 misfire on cylinders 4, 5, 6 respectively. The MIL is now blinking. After resetting the codes I get the following error code, P0300 which is the error code for random / multiple Cylinder missing. The spectrum of solutions range from replacing spark plugs to replace the engine, yikes. Replacing the engine will cost more then the value of the car. If engine replacement is needed, I hope to find a ‘minimum for your trade’ and get a new car. Thanks in advance for your help and advice. What a great way to start 2009!
