Hey Scotty I have a 2009 GMC Sierra 2500HD pick up, automatic 110k miles, I have a check engine light on for a random misfire and also said either cats or oxygen sensor and right now the truck isn’t running correctly, from 0-15mph it makes a really loud noise almost like my position is about to blow and at idle it’s very rough and makes all kinds of noises, what should I check to fix this problem, also is it safe to drive it ? Thank you
Clarification: Can you list all the P codes?
