    03 GTX SC running rough

    My wife mentiond that her GTX SC seemed to have lost some speed a few weeks ago, but said it was still running ok.
    I warmed it up on the hose today to check the oil, and when I reved it up to blow the water out, it stumbled at the higher rpm, and appeared to be running out of balance, like only on two cylinders.
    I swapped the plugs with another fairly new/used set, and it made a slight improvement, but still acted the same way.
    I also just noticed the MAINT message is blinking when I first put the key on.
    Any clue what the issue might be?

    The Maint is displayed as a reminder to get service. IIRC, it comes on every 50 hours. Mine came on at around and is still around at 110 hours. I have read that the when the '08 SCICs display Maint you need to take it in to the dealer or it will go into limp mode somewhere around 5 hours later.

    Thanks for the reply, I solved the problem with new spark plugs, then decided to trade it in on a brand new leftover 07 RXT!
