This bulletin supersedes TSB 18-09-95.

Models: 1994 - 1995 (BR) Ram PickUp

NOTE: THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH AN 8.0L V10 ENGINE BUILT PRIOR TO 2/14/94 (MDH 02-14-XX).

Symptom/Condition:

Engine miss and/or rough idle may be experienced. The cause of the engine miss and/or rough idle may be the secondary ignition cables shorting at the coil boot.

Diagnosis: 

This condition will normally show NO fault codes. It may mislead the technician into diagnosing this problem as being related to a base engine component malfunction, such as stuck lifters or valve train problems.

If the vehicle is brought in for service with vehicle performance complaints (rough idle, engine miss), and the DRB scantool does not show any fault codes, check ignition cables for the date code of 1st quarter 1994 (1-94) or earlier. The date code will appear as follows:

NOTE: DATE CODING IS DONE QUARTERLY ON WIRES. eXAMPLE IS GIVEN BELOW.

MOPAR ELECTRONIC SUPRESSION  GX 1-94  AATH


GX = Material Code

1-94 = Date Code - Represents the 1st quarter of 1994

AATH = Vendor Identification

 

NOTE:   IF THE IGNITION CABLES ARE FOUND TO BE DATED THE FIRST QUARTER OF 1994 (1/94) OR EARLIER, THEY SHOULD BE REPLACED WITH CABLES DATED 2ND QUARTER (2/940 OR LATER.

Notes: 

Policy:    Information Only
