Engine - Detonation

Number 83-T-61 Section 6 Date 11/83
Subject: DETONATION OF 2.8L V-6 ENGINES
(CODE X) - 1983 6000'S
Some 1983 6000 vehicles equiped with 2.8L V-6 engines may exhibit engine detonation. On vehicles not repaired to the procedure outlined in the Shop Manual, retarding the base engine timing 4~ is permissible. Base engine timing is now 10~ BTDC, recommended base timing for cars with detonation is 6~ BTDC. This change will alleviate the detonation problem.
