Wow, we just went thru this on a 16 SS Camaro that my buddy installed a P1 SC on. However his had a miss before he did the install. After the install he still had one and we decided it had to be plugs and wires. He replaced those but still had a miss so we couldn't finish the tune. He decided he'd replace the springs, pushrods just to make sure he didn't have a broken spring. That didn't work either so he just had a feeling it could be a ground so he builds chassis for a living and had a ground kit laying around so he ran a new ground up front on the passenger side and it quit missing so we could finish the tune.
