For DIY diagnosing/repairing/modding, the FSM is the place to start. It can be intimidating if you are new to working on cars and Nissan sometimes has some weird nomenclature but it is what a Nissan tech will use (along with CONSULT software - if you have to ask how much, you can't afford it) if you take it to a dealer.

I've been assuming that was the gauge's startup self-test. If he's actually revving that high, it would explain a lot.

Was the car wrecked? Your other posts make it seem like it was in an accident. Was there a lot of damage?

Why would you rev a cold engine to 7-8 kRPM?

Could also be the throttle position sensor(s) (or the actuator(s)) on the throttle body(s). Search this site for "throttle relearn".

Yes. Not likely to do immediate damage to an engine in good shape but it takes a few minutes off its lifespan. Bumping the limiter, even when warmed up, is not something to get in the habit of doing unless you can afford to fix things when they break.
