Hi, Welcome to Just Answer!


This is a classic description of a failing Ignition module. Have it replaced and your problem will be gone.



NOTE: It is imperative that silicone lubricant be used under the module when it is installed, to prevent module failure due to overheating.

  1. Disconnect the negative battery cable.
  2. Remove the intake manifold plenum extension.
  3. If necessary for access, tag and disconnect the spark plug wires from the distributor cap.
  4. Remove the distributor cap and rotor, as outlined in Section 1 of this manual.
  5. Unfasten the 2 module attaching screws, then lift the module up. Note the colors of the module leads, then disconnect them from the module.
    Fig. 1: Remove the 2 ignition module retaining bolts

    Fig. 2: Lift the module from the distributor, note the connector colors . . .

    Fig. 3: . . . then detach the connectors and remove the module from the vehicle


  6. If installing a new module, wipe the old silicone grease from the module and distributor base. If reinstalling the removed module, do NOT wipe the grease from the module or distributor base.
    Fig. 4: Before installing the ignition module, apply silicone grease to the module to aid in heat dissipation

    To install:

    NOTE: If installing a new module, a packet of silicone grease will be included in the kit. Spread the grease on the metal face of the module and on the distributor base where the module seats. The grease is essential for module cooling.


  7. Attach the leads to the module, noting the color code.
  8. Install the module and secure with the retaining screws. Tighten the screws to 18 inch lbs. (2 Nm).
  9. Install the rotor and distributor cap, as outlined in Section 1 of this manual.
  10. If removed, connect the spark plug wires, as tagged during removal.
  11. Install the intake manifold plenum extension.
  12. Connect the negative battery cable.

It is the only thing that would cause it to act the way that it is. And lucky for you the part is fairly inexpensive. Cost of part is around $20.00 P/N LX315T <click to go to link to buy part online
