GTX 4-TEC Runs Rough

[JBGuenther]

My 4-TEC runs rough and breaks up. The spark plugs look prestine with proper gap and no fault codes have been set. Any suggestions?

Change the spark plugs and see if its better.

New plugs corrected it...amazing, no visual evidence what so ever that there is a problem with the removed plugs...thanks much.
