    Please read these plugs and comment

    Unknown hours. They appeared to be indexed properly. Gaps were all too wide. from .030 to .037.

    I have a low speed intermittent miss, stumble.

    Looking for ideas before I pull the injectors and send them off for service.

    Thanks

    Check compression first, replace and index plugs, then test run.

    .28 - .30" is the gap for your QC8WEP plugs as long as the 200HO is at least a 2009 model.
