[QUOTE="TROY66/68, post: 456267, member: 19835"] X2. The dreaded G104 ground lug on the passenger side engine block. Had the same issue (codes) with my pre heat mode on the O2 sensors. Think it is the ground for the EGR and back up lamps as well. Like South Main Auto videos. I watched him replace a relay for that pain in the Ass TIPM. He had it all apart like the Lego I played with in the 60s. LOL [/QUOTE]
