I have a 87 Camry 2.0 5 speed and have a question on what kind of throttle body cleaner to use to clean the throttle body? I ask this because the car is so old and there are many kinds i.e. Deep creek sea foam, throttle body cleaner, and many others. Please advise me on the best one to use as I am afraid of using a brand/kind that might damage the IAC unit. Thanks for your help in this matter.
