throttle body causes bad idle throttle body causes bad idle throttle body causes bad idle

The throttle body gets dirty very fast causing a sudden idle spike every 5 seconds. To correct this you have to remove the throttle body and spray it with throttle body cleaner and wipe clean with a rag. If it is not looked after it can cause damage to the throttle body computer and or throttle plate itself. there was also oxidization on the and around the seal area after 12k km's which was starting to cause a improper seal. The throttle body required a proper torqueing. The bolts were loose and not to spec, as well.
