Anybody know when Nissan fixed the exhaust studs popping off on the 3.0 motor? My mechanic wasn't sure, but his experience was that if it didn't happen after 30K, then it wasn't likely to go bad. Every now and then I swear I hear some kind of blatting noise from around there, but maybe my overly imaginative brain
2nd, mechanic can't tell me which oxy sensor went bad. Is there a pattern that anyone knows about? The cel is one about a third of the time, when I can find a job I'd like to take a crack at it. Thanks, Dan
