Hi,
My 2004 Range Rover is driving me crazy. I was just driving down the road and truck started to misfire and SES light started flashing. I limped it to the parts store and it read codes P1300 P0301 and some other for MAF. I changed all the plugs on it switched coils around and changed PCV valve. Started it back up and all codes where gone, but the p0301!! It is driving me crazy so some1 plz help!! Don't know what to do next!

 

Did you replace the plug wires too?
If so what brand of wires did you use?

 

I did not change the wires on it and as far as I know of it still has factory wires on it. Are the Range Rover wires known to fail. For what it is worth I did pull the coil and insert a plug and it dose fire, but i'm not sure if the right amount.

 

04 range rover has a coil on plug. No plug wires. if it doesn't change then do a fuel pressure test to check for issues with fuel injectors and check compression as well.
