    My son has a 2001 Accent (the largere 1.6 liter engine) that just started
    to misfire. He went to an Autozone and the guy there said the code was a
    misfire in no.1 cylinder. He checked the plug and the plug wire and he
    said it looked OK. Could a bad injector cause this misfire?? What kind of
    a job is an injector replacement??

    Thanks for any help!

    FIRST, replace or swap the plug to a different cylinder. Heck, replace them
    all! I've got a 2004 T&C that idled like crap. Dealer said it was normal. It
    and finally threw a misfire code. I swapped wires, same cylinder. I checked
    the plug, and it looked and fired fine in open air. Same resistance as the
    others. I swapped the plug to a different cylinder, and the misfire code
    folllowed the plug. Ran fine ever since. DC finally came out with a TSB that
    says replace plugs and wires if the 2K4 T&C shows up with a misfire code.
    Looks and open air firing isn't everything.

    Injector replacement? Alot harder and more $$$$$ than plug replacement.

    It's probably the wire. With the car off, pull the wire loose from the
    plug and let it just rest back on the plug. Then start the car.
    Gradually lift the wire back off the plug and look for arcing. You
    probably have an arc out the side of the insulator tube to the metal tube
    on the head.

    I have had an ongoing issue with my '02. It was finally determined that
    air in the fuel line was causing a false misfire code. The most common
    causes of misfiring is the plugs/wires. Get Hyundai brand only, many
    dealers "claim" that non-factory plugs/wires can cause misfiring. If
    the issues persist is may be a dirty injector (try using injector
    cleaner.) There can also be a very large number of other possible
    causes, low compression, bad coil...

    My son installed a new set of plugs today and he said he verified that
    there is spark at the end of each wire.
    He still has a miss.
    Would you still reccomend getting new plug wires???

    Do what Hyundaitech said. It takes ALOT more voltage to fire a plug under
    cylinder pressure. It could easily be flashing over outside the plug under

    Even if your wire is not arcing where I think it will, it's likely to
    produce an arc from wherever the misfire is occurring if you've got an
    ignition misfire.
