2002 Taurus problem.

Discussion in 'Car Forum' started by Kentuckian, Dec 29, 2005.

  1. My wife's 2002 Taurus has been difficult to start on cold mornings lately, and with 72,000 miles on it I decided to change out the spark plugs.

    The factory gap setting is .044, and all the gaps had opened up to about .065.

    I changed them out and took the car out for a drive, and under heavy acceleration it would begin stumbling and had no power. The check engine light came on, so I took it to Advance Auto Parts where I bought the plugs. They read the code, and it said "cylinder 1 misfire". I figured the plug must be bad, so I bought another plug and changed it out, but it didn't fix the problem. I then thought that perhaps the connector in the plug wire had separated when I replaced the plug, so I bought a set of wires and replaced the wire for #1 cylinder. That seemed to fix the problem initially, but on the way home it started acting up again.

    The only thing left, as far as I can tell, is the coil itself. Is it possible that the new plugs caused the coil to go bad? I swapped out the plugs one at a time, so I know the wires aren't crossed.

    Any ideas?

    I like annoying people.
    Pick up some seafoam or chevron techtrolin (something like that spelling) put one in the tank and run one thru the vacuum system. I have found alot of problems with carbon buildup causing missfire codes even after doing a tuneup. You may also want to do a compression test.
     

  3. The code reader at Advance Auto Parts must be screwy, because I found out through a little trial and error that the problem was a bad spark plug in cylinder #2, rather than #1.

    ;g

    At any rate....it's fixed. :cool:
