guys, I need lots of help. I am having problems with my 99 NSXT. 1)the car pulls to either side during hard breaking (dealers said tire problems) 2) car rattles and shakes violently above 120 mph (dealer said tires again) 3) Car jerks when back off on throttle off the first gear when not warmed up (is this normal) 4) regardless of what rpm I start when going into first gear, there is a lot of clutch chatter (car shakes, vibration in the clutch pedal when depressed above 6000rpm (dealer contribute these problem due to worn clutch) Okay, so far I have 18000 miles, are all these problems normal wear and tear problem? Are deals diagnostics right on target?
