My 2004 Land Rover Discovery II

Is Shooting These Codes

P0300 - Random Multiple Cylinder Misfire
- P0301 - Cylinder 1 Misfire
- P0306 - Cylinder 6 Misfire

P1300 - Manufacturers Control Ignition Misfire

Anyone have any ideas?
I've replaced the spark plugs but the car is still misfiring.

 

Have you replaced the plug wires?
I am going to go ahead and assume not because if you had the mis fires would go away.
www.apexperformance.net, get the Magnecore plug wires.

 

Sounds like your pretty much sure its the wires.

No chance its the coil packs or maf?

 

its not the maf, they don't throw misfire codes.

but its likely the coil. six and one share the same line.
Sometimes a broken wire on say number six can cause issues but most of the time its the coil.

 

Yeah thats why I thought it might have been the coil pack.
But if it was the coil pack wouldn't 4 cylinders be misfiring and not two?

 

I accept with information: P0300 - Random Multiple Cylinder Misfire; P0301 - Cylinder 1 Misfire; P0306 - Cylinder 6 Misfire; P1300 - Manufacturers Control Ignition Misfire

 

What?
