    Car is idling rough, sounds like it is missing?

    My car is idling rough and sounds like it is missing and I have had a hard time starting it lately. What could be causing this, plugs, coil pack ...? Can anyone help me out so I can get it taken car of under warranty when I take it in. Thanks, Matt

    the TR6's miss a little at idle.... i think if you run brisk plugs it fixs the "miss at idle issues".

    Mine has a miss in it too. Seems to get worse after I have been driving hard. I have the stock plugs in mine.

    I believe they have a TSB on the 03's, not shure on the 04's for the Coil on Plug. Mine is having a hard time starting sometimes as well. I have a set of NGKTR6's but I am going to let the dealer take a look at it first I guess.

    Have you even pulled the plugs to take a look at them? Thats would be a good place to start and give you some idea of whats going on.

    I am taking my car into the dealer to get the TOB replaced, and hopefully the clutch, so I will mention this to them as well.
