Test 3: Intake/Exhaust Restriction: Purpose

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2002 Ford RV Cutaway, 2002 Ford Pickup, 2002 Ford F550 Super Duty, 2002 Ford F450 Super Duty, and 2002 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.

This is a visual inspection to determine if an air intake or exhaust restriction is contributing to a hard start or no-start condition. If engine does start and an air intake or exhaust restriction exists, a large amount of Black/Blue smoke will be produced.
