Looking at buying this land rover that's throwing a couple codes but if it guys too expensive I'll by something else. Here are the codes. P0303,, p0307, p1300 and p0174. I know they pretty much all have to do with misfiring but what could be causing all of it? Any help woulx be great. Thanks

 

No one knows what could be throwing these codes? Could both coils be bad? Wires plugs? O2 sensors?

 

You gave us no help with this, how many miles on it, when was it last tuned along with 8 mm silicone wires and yes, have the 02's been changed.
How much is he asking for it and have you taken it to a shop for a prepurchase inspection yet?
