[QUOTE="Genesiss, post: 444013, member: 22628"] So I got the oil filter, no change. What I did discover is this model and year doesn’t monitor the oil pressure through the ecm. It appears the red oil light is just a pressure switch. It’s was able to get it to turn off if I grounded it out. I also bled any air pressure trapped by loosening the filter slightly and running the engine briefly to ensure my mechanic didn’t screw up and didn’t prime it. I have an oil pressure gauge I’ll be connecting today to verify actual pressure. The bad part is after the engine replacement with the rebuilt and now a rebuilt pcm I no longer have 02 sensor codes but I do have the p0344 now and with the larger tires I have the tpsm light and it’s still in limp mode. Some say you should only use Mopar parts but others say lately Mopar is no better then aftermarket on sensors. Part of me thinks the tipm is also trashed and causing some issues. Has anyone paid for a professional tune to simply eliminate the limp mode feature? It seems like so many non essential issues can cause this mode. [/QUOTE]
