Ls-1 misfire
Misfire under a load from 3k rpm on up. No code , flashing cel . Replaced plugs with NGK TR-6, misfire went away for a week, now back , idle is good but pops every now and then . I do have a cam and centrifugal supercharger . My plug wires are relatively new. Any ideas ??

If you have headers it's a good idea to pull all plug wires and check them closely. I had a problem with #4 wire being burnt but couldn't tell until I took the wire off and checked. Just a small crack but enough to arc.
