Use this section to find the correct test procedure for a given symptom. The symptoms and actions in this section are Emission related only. Refer to COMPUTERS AND CONTROL SYSTEMS for complete Diagnosis By Symptom for Fuel, Ignition, Computerized Engine Controls and Emissions.

FLOW OF DIAGNOSIS
Always use the Flow of Diagnosis for proper testing sequence. Verify the correct system application to ensure that the vehicle has the given component(s).

VISUAL INSPECTION
Before proceding to the appropriate symptom perform the following inspection:

1 Vacuum hoses for splits, kinks and proper routing.
2 Ignition wires for cracking, hardness and proper connections at both the distributor and spark plugs.
3 All wiring for proper connections, pinches, routing, and cuts.

NOTE: Ensure that the engine is at operating temperature before inspecting emission control system operation (except when attempting to diagnosis a cold driveablity problem). The catalytic converter and feedback systems will not function as designed if this is not achieved and will result in inaccurate test results.
