Gentlemen. I need your advice. I purchased a 2003 Marauder with 144k miles on 1/10. The vehicle appeared to be in great condition. Only noticeable adds were K&N air filter. Monday I had a state inspection done. When I drove home the check engine light came on and there is a slight shimmer in the idle. Also, when 1st and 2nd transition there is a slight vibration. Any info would help guys and gals. If just curious as to what I'm getting into and what possibly could cause this.
God bless.
JIMMY
