You can call customer relation or try a different dealer. The dealer is just a middleman. Don't tell them you pulled your own codes. Play dumb.

And i would asume that if i can tell if any 2000 and up Acuras have been over reved that Mitsu could aswell. Doesn't set a code just stays in freeze data.

The TSX used to jump teeth al the time mostly due to low oil and gear wear, According the powers that be at Honda a chain can not stretch it slips because of gear wear.
