    06 Cadillac cts misfire

    I have a 2006 Cadillac cts that has had codes for a misfire on all 6 cylinders. Before I digg any deeper into, what might be causing the misfire?

    Plugs and coil packs are a good start...

    All 6 leads me more towards a timing issue though.

    I am having the same problem.. Codes came back as misfires for all 6 cylinders... Did you replace the plugs and coils or was it the timing chain? Or was it something else?

    On my car the coils are under the intake plenum. The engine cover foam comes no where near them, and I thought the foam was the closed cell type that won't absorb or hold moisture.

    If u have a 3.6 like the rest of us yes its very close. Coils are almost accessible without taking off the upper intake plenum and you evgine covers around the top outside of tour engine. And if the foams closed cell why does it retain oil or soot or get dirty at all. Get off you high horse homie ur shit smells just as bad as mine. I dought the biggest cadillac dealership in michigan woyld have a bunch of dipshits working there. If u think all six coils and plugs are bad ur silly. If the Ecu was bad ur shit would barly run. Leaves it down to electrical considering you have your services done on time. What messes w electical more than moisture and dirt. At the very least disconnect all your sensors and coils and clean them. W any luck it could be a loose connection

    Had the same problem only a misfire on 3 cylinders on my 2.8L, only getting 25lbs of compression out of the engine and mechanic recommends rebuild/replace engine due to known Cadillac Timing Chain issue (jumped and then bent the valves).
