So I’m looking into buying this guys 03 lancer oz rally edition but he ran diagnostics and two codes came back P0421 and P0302. I know the first is cat below threshold and the second is cylinder 2 misfiring. What I want to know is when I go to take a look at the car, what should I be checking to make sure I’m not buying a car that’s going to cost me more money than it’s worth? Or can you already tell it’s not worth it just by those codes. Any other suggestions would be appreciated too. Thanks!
I think that'd depend on how much use you think you'd get out of it? You could always rent one from a local parts store if you don't want to spend the money on a good test set.
If I was the perspective buyer here, I'd probably settle for an audible relative compression test. Quick, simple, and doesn't require any disassembly. If I didn't hear an issue, I'd roll with it.
