Throttle Body (TBI,inlet manifold control flap)

TBI provides the optimum mixture ratio of air and fuel at all stages of combustion. TBI has immediate response characteristics to constantly changing conditions and allows the engine to run with the leanest possible air / fuel mixture ratio, greatly reducing exhaust gas emissions.

Failure Symptoms
A bad throttle body by reading the error  codes with an OBD II reader. The throttle body can also be examined  for leaks or linkage issues.
