[QUOTE="SCGallo2, post: 17033386, member: 160791"] Could be a coil pack not fully seated on the plug, loose spark plug blowout (unlikely), or loose coil pack connector if not reinstalled correctly. I take my time and pay close attention to detail when replacing my spark plugs. Check electrical and vacuum connections on your CAI and anything else removed during recent maintenance. If cylinder damage, this would be your second hurt motor, right? A quality tune and fresh top-tier octane are essential for a happy engine. If fuel sits in my tank for over a month, I burn it all out and fill up with fresh Shell 93 octane before going WOT. [/QUOTE]
