Symptoms..... CEL went flashy yesterday on my way home from work. Codes: P0300 (Random/Multiple Missfire), P0301 (Cylinder 1 Missfire), P0306 (Cylinder 6 Missfire), P1301 (Manufacturer specific DTC). The truck feels really under power. I guess as a result of running on only 6 cylinders. The engine shakes more than usual. Recently changed battery and alternator. Truck profile: 2004 Disco,just hit 60,059 miles. Ahhh yes, and just out of warranty. Always used 93 octane.

I had just ordered plugs and wire set for a 60k tune up. Will changing plugs and wires set alone solve the problem? Is there anything else that I should be looking at? Please advise. Any help is greatly appreciated.

 

Will new plugs and wires fix this? That depends on the plug wires that you are going to be useing.
As long as you use Magnecor plug wires your problem will go away.

 

Thanks for your reply Spike555. I will have to sit out till Monday for the delivery of the parts.

 

when i do the wires in my rig i am going to try and relocate my coil. its in a dumb place,,,,,
