Rough Idle on occasion

chuckd05

My car since I picked it up from a shop on thursday has been idleing rough and the car has thrown the p1033 or whatever it is... o2 sensor code...

I know my secondary o2s were disconnected and are extended for my LTH but i dont think those failing would cause the rough idle...

My car was recently retuned and should be running proper a/f ... could one of my primary o2's be bad or could this be caused by something else..

the tranny was out and new flywheel was put in, I doubt it was caused by any of that, but the issue did start on the way home. I am going to try to look over things down there tomorrow if the rain stays away, but as of now i am curious if anyone on here has had a rough idle, similar to a cam, and a few hundred rpm's lower than usual... but not all the time. Occasionaly it happens, and if i give it a quick little rev sometimes it stops..

lmk if you have any ideas , thanks !

I have full bolt ons, G3, PE LTH, Stillen exhaust, fidanza flywheel, stillen crank pulley, going to the dealer for something like this isnt really the best idea but I may end up doing it anyway... I have a great relationship with them and they will charge me a discounted labor rate, and atleast should have the best tools to check codes and trouble shoot... I do trust my dealer as I am lucky to have mechanics there I know I can trust..
