I am getting a CEL w/ misfire on 2 and 4 occasionally. My CEL has come on 2 times now - the dealer cleared it for me ($) the first time and mentioned the plugs were OEM (@58k miles). I checked the plugs, but they weren't OEM. Turns out - the ones they checked (LH side, 2 and 4) were OEM Champions that looked like crap and the ones I checked were NGKs..... Guess I have to wonder WTF the previous owner did....

So I changed the plugs and wires. Then, I got another CEL. Instead of taking it back to the dealer and paying them to do it again, I got a neat-o car code program. I cleared my CEL and will wait and see what happens, but what's next - the coil? Sheesh. Anyone had this happen before?
