What would be the symptoms?

Your car would run like shiot and sound like its missing alot. because if 1 tooth is off it makes everything else off

10% down on power. idle a bit rough.

Random misfire and whats listed above

And if that is the problem, what is the best way to get it back the way it is supposed to be?

PM me and I'll take a look at it. I go to school in Redlands, just not today; midterm. Thursday is good though. I want to be able to hear and feel what is going on, most likely I can diagnose it and help you fix it, peace.

Did you do cams or recently have your TB off or something? I have never seen one off from the factory.

If you cover is on a loose belt is the only thing that would allow this to happen.

If it skips one tooth it is gonna skip a bunch more and eat your valves.

Sorry to bring this back from the dead, but would a car not mis if a tooth is off and ONLY be down on power?
