Random Misfire
I removed passenger side valve cover, and hand cranked the motor. I found #6 loose and not moving. I thought I heard tapping coming from both sides. Is there a possibility that two AMF lifters will stick?

I did everything you showed me to. The '09 Suburban with 205k miles has the lifter released, DOD deleted, new spark plugs, same old gaskets. She has 38-40 psi oil pressure at idle and 45 psi at 1500rpms. I am so grateful for your time. I'll throw you a bone when I recover financially. Go America!!
