Sorry, I had to make to a business before 5 P.M, being it's Friday and all. Here are the rest of the tests. Yes you can clean the throttle plate and throttle body, but I wouldn't use anything like brake or carb cleaner. It's much to harsh, and be very carefull of your Throttle Position Sensor(TPS) and other electronics that may be damaged. You might want to run these tests first and track down the exact problem first.
