    There is definitely a TSB out there to reprogram the ECM to raise the idle a bit on the 3.2...I just can't find it!

    O yea some dealers are sneaky, they deal with Cadillacs on a daily basics and know exactly what all common problems are with any Cadillac cts, they think everyone is car stupid or something. You have to be aggressive with them, I tried that Mr civil nice guy with them and they tried to charge me over 700 bucks to replace my ecm, which was under recall because it was faulty to began with, after I got hostile not physical but raised my voice at them did one of them say o yes I know what your talking about its a recall don't charge that man, I call b.s on it because since they are in dependent contractors they were going to see if I would have paid it, and I bet they play that clueless game with anyone they think they can get over! O yes and mine started over the gas issue and then they said they couldn't reflash it and it had to be replaced because it was faulty.
