low rpm miss/stumble
2002 Z06 with 52,000. New plugs and wires about 5000 miles ago. It has a slight miss/ stumble at about 1000 rpms, but only under load. Not there if in neutral.. No indication of miss on tach and usually only happens in 4th gear, although yesterday on a road trip it started happening in 5th. The temp was in the high 80s low 90s when this happened yesterday but is fairly consistent in 4th on most days. Techron very other tankful. Goes away after rpms go up over about 1100 rpms. No codes. Any ideas? Thanks in advance.

Without putting a scan tool or a scope on the engine you'd only be guessing....dirty fuel filter, dirty MAF, dirty throttle body, maybe an injector misfire...take your pick !!!
