What to look for on 03
Just wanted to see if ya'll had anything else to add!Common issues would be column lock, and uhmm... extreme tire wear
Other, a little less common issues are: fuel filler hose not working right at some gas stations (TSB), issues with pop-up lights, bent shift forks (less likely in later 03 models as they got steel forks upgrade), leaky rear diff, alignment not set correcty at the dealer (unusual wear patterns on the front tires).
I am not saying any z06 will have all these, just what different people are reporting.
Some things will sound/feel like a problem but they are normal (according to GM):
exhaust h-pipe jingle (sometimes fixed by TSB, sometimes explained away as "by design"), ticking injectors at lower RPM, rattles/clanks when taking off in 1st , rattle when shutting down, some oil consumption.
