We have seen several things cause this condition on this vehicle, here are the most common things that need to be checked.

. Verify the 4 screws in the Fuse Block-Underhood are all tight. These bolts tighten the connectors on the bottom side.

Check the 38 cavity connector C111 at the LF strut tower for a poor connection.

Check Ground G112 under the Ignition Control Module for a poor connection.

Wiggle tug test all under hood wiring and connections.

It is my goal to give you 5 star service, so please give me a five star rating before leaving the site today.
