5th Fuel Injector Misfiring

I don't remember the code. I just remember the guy telling me that the injector was misfiring and that it was affecting a sensor in the transmission. I was upset at the time because I had just replaced the fuel injector as I had been advised to do. I am trying to sell the vehicle and I was contacted by a gentleman and he told me that this was a common problem with Hyundais, that it has a burnt valve and that the engine needs to be torn down, and the heads resurfaced and I wanted to see if this was at all possible.

Thanks for the information, I didn't think that what he told me was true, as I said I am trying to sell it because I don't have the time or money to fix it and I felt like he was telling me that because he wanted me to buy it for a price that is way less than what it is worth.

I work at a hyundai dealership and never ran into something like that, without knowing what the actual code is it wil just be a guessing game. Have you done any tune ups on the vehicle? You might just have a bad spark plug or wire.

Thanks for your response, I wish I had written the code down. I have had a tune up, replaced both spark plugs and wires.

Was the code even erased after the repair?
