NOTE: Refer to Connector Test Adapter Kit J 35616-A Notice in Service Precautions.
Several of the symptom procedures call for a careful visual and physical inspection. This can lead to correcting a problem without further tests and can save valuable time. This inspection should include the following areas:
^ Inspect the PCM grounds for being clean, tight, and in their proper location. Refer to Master Electrical Component List and Power and Grounding Connector End Views in Diagrams.
^ Inspect vacuum hoses for splits, kinks, and proper connections, as shown on Vehicle Emission Control Information label. Inspect thoroughly for any type of leak or restriction. Refer to Emission Hose Routing Diagram.
^ Inspect the air intake ducts for being collapsed, damaged areas, looseness, improper installation, or leaking, especially between the MAF sensor and the throttle body.
^ Inspect for air leaks at throttle body mounting area, Mass Air Flow (MAF) sensor and intake manifold sealing surfaces.
^ Inspect the wiring harness for poor connections, pinches, cuts, or other damage.
^ Inspect for loose, damaged, or missing sensors/components.
Use the following tables when diagnosing a symptom complaint:
^ Hard Start
^ Surges/Chuggles
^ Lack of Power, Sluggishness, or Sponginess
^ Detonation/Spark Knock
^ Hesitation, Sag, Stumble
^ Cuts Out, Misses
^ Poor Fuel Economy
^ Poor Fuel Fill Quality
^ Rough, Unstable, or Incorrect Idle and Stalling
^ Dieseling, Run-On
^ Backfire
^ Engine Cranks but Does Not Run
^ Malfunction Indicator Lamp (MIL) Inoperative
^ Malfunction Indicator Lamp (MIL) Always On

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
