06 GTO Performance Questions
I recently purchased a 2006 GTO with M6 and 69000 miles and have a few questions about my performance.First off it runs rich but only on 1 side looking at the tailpipes one is clean and the other pretty black,is it possible for an o2 sensor to make one side run richer than the other? Second if I take off in first gear going about 10-15mph and smash the gas it will not break the tires loose is this normal? trac control off with 275/40/17 tires.Also it pulls real good but when I reach about 3500-4000 rpm its like I push a nitro button and it really kicks in, normal?Any input would be great. Thanks By the way i know the miles are a little high but I got the car for $14500, so a little money spent isnt a bad thing.
