2003 Jerking/Misting while driving

WOW... I am having same issue now with mine! Trying to find ANYTHING on this has been rather hard to say the least. As your dad, I have had my scanner on this several times, an not 1 code has popped up. I only know I do know, is, it seems to only happen after reaching operating temp. I did get this to happen in Park for the first time yesterday trying yet again to fix the problem. To me, it seems as if something is shutting off the engine at anytime it like to. this is brief, yet drive lets say 55mph an for 1/2 sec. engine shut off, then comes back on, can be a real scare. Not to mention the hard jerking, due to still being in drive. Transmission/drive-train, all hooked up. crazy! also rather worrisome. My wife told me this, thought she was nutz.... next moring going to work, she brought back the car, told me, "DRIVE IT, am taking your ride today..." This is a problem, PLS let me know what your dad has done, or come up with! I have checked all wires under the hood. I have checked for any vacuum leaks, found none! Like I said prior, I have no code to even work with, so have been checking the basic's ... and again, I have found nothing wrong yet. hopefully I can find something to pass along.

I know it's probably been solved by now but incase someone else has the same problem. All this is caused by a piece of plastic holding some wires (plastic breaks). The wire hangs over one of your pulleys and it gets exposed due to be rubbed by the pulley. You can tape it up and away from the pulley and the car will run perfect. It will normally only act up when driving forward due to the motor tilting when accelerating. Hope this helps because I thought my 2006 Buick rendezvous was needing to be junked

@Adam. After reading your post I ran to the SUV and checked all the wires near the pulleys,

Sorry Adam, I pressed the wrong button. Anyway I checked the wires near the pulleys and the only one I found looks like it goes to a sensor and its located behind the AC pulley I believe, I don't think its that one because I started the car, which runs very smooth, I wiggled those wires, push and pulled on them but nothing happenedso I did the same with all the wires I could reach, determined that wasn't the problem. QUESTION: Could you please tell me the location of the wires you are referring to? BTW So far, I have invested about $900 under advise from various "professional" and responsible mechanics, who suggested I replace the Catalytic converter, vacuum hoses, full tune up, electronic fuel control valve etc.. :-( Thank you in advance.
