I am having a 6.2 2011 SVT engine problem, half a day after the Safety Recall Flash done to my truck. I get a lower RPM of 500 to 700. This noticable Ticking sound from passenger side of the Motor. Under the VCovers. Now I need to be able to make it back to the dealer and find out what is going on. I never had a Ticking from my motor before that. Any ideas?
