My 2006 GTI SE is "Stuttering" when I get to about 4,000 to 5,000 RPM's and backfiring through the exhaust. Sounds exactly like the REV Limiter on my Harley-Davidson when I get over a set RPM. Anyone have this experience? Here are my codes from Candoo Pro. Any suggestions on what I should...

All the bearings on this crankshaft are not bad. When I rotate them with my fingers, I don't feel any roughness. Whole shaft is in pretty good shape. The bearing that is circled in red, is not rough either, but is has a chingy sound to it when I spin it. Is this bearing bad or good? Is this...
