    2003 Mercury Marauder

    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.

    Go to a FLAPS and have them read the code(s). Post them here. Just a shot in the dark without the code(s)

    Good morning Gents. The shop this morning advised me that 2 codes were making my check engine light come on.
    PO302 and PO308. Any info from you experts will help.
    Thank Jimmy

    ^^^what myrodr said^^^

    Replace all 8 spark plugs unless you have evidence they are relatively new. If that isn't it, then you have 2 COPs on their way out.

    Did you leave the car for the inspection? What are the chances the tech "test drove" your car? I changed shops when I found a new set of "stripes" in the street in front of the shop when I picked it up!
    Rough treatment may have left you with new problems.

    I won't be wronged. I won't be insulted. I won't be laid a-hand on. I don't do these things to other people, and I require the same from them.

    Good evening gents. All 8 spark plugs have been replaced and I'm still experiencing a rough idle and pause in the engine.

    Cops are cheap, and with 144k on the clock, a good investment.
