BEFORE YOU BEGIN

Make a thorough check before starting any test

procedure and fix any known mechanical prob-

lems before performing any test. Loose or dam-

aged hoses, wiring, or electrical connectors are

often responsible for poor engine performance.

Refer to your vehicle’s service manual for

proper connection of vacuum hoses, electrical

wiring, and wiring harness connectors. Check

the following areas:

■ All fluid levels

■ Spark plugs and spark plug wires

■ Air cleaner

■ Vacuum hoses

■ Belts

■ Electrical wiring

■ Electrical connectors

ENGINE PREPARATION BEFORE

TIMING

Always prepare the engine for timing before

performing a timing check. Refer to the Vehicle

Emission Control Label or service manual for

timing procedures and specifications for your

vehicle. The Vehicle Emission Control Label is

located under the hood in the engine

compartment. The label is typically located on

the underside of the hood, on a fender well or

valve cover, or near the hood latch.
