Course: Automotive Technology III (20104-III) > Section: ENGINE PERFORMANCE: Fuel, Air Induction, and Exhaust Systems

Procedure should include conducting tests, using

- vacuum gauge
- fuel pressure gauge/back pressure gauge
- oxygen (O2) sensor or air pump
- DMM with pressure transducers.

Process/Skill Questions:

- What performance problems might be caused by a restricted exhaust?
- What DTC could be prompted by a restricted exhaust?
- What problems might be caused by low exhaust back pressure?
