just bought the car a little while ago. it has full cat back borla with a test pipe. car runs great with 170xxx on it, but I have noticed the at low rpm giving it a good amount of gas I'm getting a sharp miss. I know about the follower in the HPFP could that be a cause before I put new plugs in it, also have no check engine light. only code I got is for a evap leak.

 

so it was nice out today so I drove her around a lot. the longer I am driving the miss is happening more. no one has any thoughts??
