ok can anyone help me out? I have a 2003 disco with 95000 miles. about 3 weeks ago my engine fan somehow fell off and punctured my water pump. replaced both and now I have a misfire on cylinders 2 and 8. replaced both plugs and wires and the codes are still showing. these are all the codes showing : p0300 p0302 p0308 p1319 . my husbands father is a pretty nifty mechanic and seems to think maybe it is the coil pack. But of course that requires removing the manifold and buying new things to replace that as well. my question is does this sound right before we do all this and buy all those things, or could there be another issue? bear with me, I know nothing about cars and in my small town everyone is afraid of land rovers, but it is my love and it seems to be spiraling into a black hole of doom right now. thanks so much for any response!

Welcome. Shop manual is a free download in my signature. Wires can be done without moving coils, but grease hands, and be inventive of home fabbed helper tools for the wires.

Take that handsome guy, hold hands, and walk in the dark of night to the truck, raise hood, and watch for small arcs when running around wires, plug boots, plugs, coils.

Norm is replace plugs and wires (with 8mm silicone).

Your post will be relocated to the D2 area.

 

Also - would suggest that you be sure water pump and fan clutch are replaced. They usually jump off the cliff together

 

yea, we already replaced the water pump, fan, fan clutch, wires and plugs. and it still awful , if not worse than before. it has a rough idle and hops all over the place until I get to coasting speed then it smoothes out.

 

Clean IACV with carb cleaner. Look for arcs.

 

thank you! I will give that a go
