    Even after new plugs were installed the engine misfires off and on. It’s a 2008 Tacoma with 181k miles. I’ve run one tank of gas with a good fuel treatment, which didn’t help. I suspect it may be a defective coil. Has anyone else had this problem?

    If you know which cylinder is missing, try swapping coils. Make sure plugs are in good shape and OE type. Any DTCs your vehicle throws will give some insight as well.

    How long have plugs been in there?

    2005 4runner from new.
    Never had an engine issue in 15 years and 200,000 miles. Runs like a top.
    Starts up like when it was new.
    Ordered a starter from Amazon that came with a lifetime warranty.
    But Amazon doesn't offer the lifetime warranty on the starter today??/??

    I called the company named on the box and the girl said if it ever fails they will send me a new one.
