Diagnostic Notes
Before proceeding to the appropriate symptom perform the following inspection:
NOTE: It is essential that the vehicle has been properly warmed up and is at operating temperature (except when attempting to diagnosis a cold driveability problem). The catalytic converter and feedback systems will not function as designed if this is not achieved. Failure to do so will result in inaccurate test results.
VISUALLY CHECK:
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.
