i have an 02 m6 ws6 just installed polluter cam,its been tuned,the car runs perfect other than after its hot it doesnt want to catch the idle right away,i have to hold the throttle for about 15,20 seconds then its fine.smells rich to me,has lt,ory,cat back.any help would be great,ive adjusted the set screw every which way,it makes it a little better but its not right.

 

Just needs more tuning. There are alot of things it could be. Thats a common problem and there are so many things that it could be. Needs correct TP voltage, correct position of the throttle blade (set screw), then spark, ve, raf, bla bla

 

thanks ill have to get back with my tuner,just starting to wonder if we can ever get it right.
