I.D. = 3451) for Code 42, Spark Knock, High Idle.
[50] Needs air injection service kit (P/N 10115773) and new vehicle emission control label.
Footnotes 51 Thru 100
[51] Must be ordered with service kit P/N 10115773.
[52] With this PROM installed, use 1987-88 2.8L speed density engine driveability and emissions manual.
[53] PROM update eliminates MAF sensor, replacing it with a speed density system. With a 1990 or earlier primary cartridge, I.D. vehicle on scanner
as a 1989 model (VIN = K-1-W).
