the check engine light might be on if you had an engine swap. check the computer read out. temp gauge might not work if the engine swap wasn't performed correctly. loupy idle might be an aftermarket cam. vtech normally around 3500 to 4000 rpms. redline... i dunno hold the pedal to the floor in neutral and see when the rev limiter kicks in. don't be afraid of the redline... it's a honda.
