Subject:
FUEL INJECTOR WIRES MAY BECOME TRAPPED WHEN REINSTALLING THE AIR CLEANER (TWIST WIRES ONCE)

Model and Year:
1988-93 LIGHT DUTY TRUCKS

THIS BULLETIN CANCELS AND SUPERSEDES DEALER SERVICE BULLETIN NO. 93-8-6C, DATED JAN. 1993. CALL LIGHT DUTY TRUCKS HAVE BEEN ADDED AS WELL AS THE REFERENCED ARTWORK REVISED.

CONDITION:





When an air cleaner is removed on 1988-93 Light duty trucks, the potential for trapping the injector wires between the air cleaner and the throttle body or between the extension ring and throttle body is present during reinstallation (Figure 1).

CORRECTION:





To reduce the possibility of such an occurrence, especially if the reason for removing the air cleaner is a pinched wire, carefully remove the injector wires. Route the green and white wire under the blue and red wire and carefully twist once (Figure 2). Reconnect injector wires.

One twist will reduce the slack in the injector wires so that there is less chance of them being trapped between the mating surfaces during assembly.
