As the title says, my service engine light came on the other day and I brought my Disco to Autozone to get the codes.

The diagnostic tool gave me:
P1300
P1590
P0304
P0302
P0304
P0302
P0300

To me, it sounds like I need to replace the plugs and wires. Am I missing anything? It’s a 2000 D2 with 145k miles on it. Thanks for your help!

 

Check for spark strength too, might have coil issues as well. If you do plugs and wires and still have those codes, I'd look into a new MAF, although there's usually other codes that go along with a bad MAF

 

 

I'd honestly replace the 40.00 (if that) coil packs while you have it all torn down to do the plugs and wires.
