    Putting

    Hello all and thank you for making me feel welcome. I bought an '08 CTS DI back when it was brand new for finishing my second deployment to Iraq. The car has been wonderful so far but I'm having a little issue. It has 75k miles on it and has had all the proper maintenance done. I just had an issue with a misfire with a coil (fixed with OEM part) but there has been an underlying "putting" sound when I hit the gas. I was wondering if it could be the spark plugs bc I did the injectors, cleaned the K&N air filter, and just replaced the bad coil. My car lacks the power I am used to it having and it is consuming more gas. Please help me!

    I thought this was going to be a golf thread.

    It's possible that your MAF is dirty. Overoiled K&N filters will do that. Just a thought.
    Have you pulled your codes?

    No idea what pulling codes means lol. But the check engine light is not on. Plus, this putting has been happening even before I put theK&N in. It started over 6 months ago and I have slowly tried everything I know and it's still there. Now it is more frequent. If I floor it, the car may go fast or it may putt and hesitate before catching.

    How to pull the DTC
    http://www.cadillacforums.com/forums...odes-dtcs.html

    The plug(s) could be fouled from the coil problem.

    I've replaced the plug to the bad coil but can the bad coil effect the other plugs?

    I don't think the CTS has the capability to pull DTC's via the DIC, nor does any Cadillac after '05 (if I remember correctly).

    Will move this to CTS forum .

    Ok please send me a link to the thread, I can't seem to find where you moved it to.

    Will these codes tell me minor things that the check engine light won't? How often should I be doing this?

    Plus I had asked if having one misfire in a coil effect the rest of the plugs? Should I just change them all?

    Have dealer run scan tool to check for codes. Do you get the monthly diagnostic report? Anything shown on that? If you dont get that report, sign up for it on the Onstar website.

    Minor detail... the monthly diagnostic report referred to in above post requires a subscription to OnStar.

    Re: Putting

    For one thing, my opinion is to never replace just one plug. Just change all 6 and take a look and smell of the old plugs coming out. They can tell you a lot about whats going on.
    You didn't say if the car was doing it idle, under load or at highway speeds. If it's only under load, I would suspect injectors. At cruising speed, I would consider the throttle body. At idle, bad plugs, bad fuel filter, bad gas.

    If it was me, i'd change all the plugs and take a good look at them. Might be that another coil is going out as well.

    Thank you very much, Laura, you and the rest of the members on this thread have been very helpful. I will be going to Vera Cadillac here in South Florida to pull up codes and take the appropriate action.

    Re: Putting

    Again, I agree with others regarding 6 plugs vs. 1 plug. You have 75 k on the clock, close enough to change them all out at this time. I also agree with CT"ess" on the bad fuel, filter as well.
