ISSUE: Stalling and/or a no-start condition on vehicles with EEC IV and certain TFI modules may be caused by moisture or salt splash entering at the upper right hand mounting hole of the TFI module housing. This condition will result in a service code 14.
ACTION: To correct this, use the following diagnostic and service procedure to seal the hole and prevent further concerns.
NOTE: The distributor does not have to be removed to perform this repair.
1. Check to see if the TFI-IV module part number suffix is A2A and the date code is 6K08 or prior, (mounting hole was sealed after 6K08). If the suffix is not A2A, use normal diagnostic procedures and do not perform Steps 2 and 3.
2. Thoroughly clean and dry upper right hand mounting hole of the TFI module with a clean paper towel.
3. Fill the cleaned hole with silicone grease (D7AZ-19A331-A).
4. Clear service code 14 from memory.
