I bought the car from someone that melted the number 2 piston. I replaced the piston, piston rings, rod, rod bearings, and had the cylinder honed. I put it back together and it seems like that cylinder isn't working correctly but it isn't throwing any codes. It is acting like a misfire because if you unplug the spark plug wire while running, it doesn't effect it. I ran with that and changed the coil pack, spark plug wires, spark plugs, I ran a compression test, leak down test and everything is in specs. If I drive it at a higher speed it seems that the cylinder is fine but it idles rough and smokes a bit. The smoke might be from the previous guy melting the piston. It dumped a lot of oil and gas in the exhaust system. My question is, could the computer just need reflashed since it passed all the tests?
have the same problem?
