Hello all, driving around today and my CEL came on. My scan master G read off codes 15, 21 and 23. The car started missing and running rough as well as the rpm went up to 1500rpm at idle. Additionally the scan master G had a reading of negative 30 degrees coolant and negative 70 for air temp. My TPS was .42 now it reads 4.54. FYI, I replaced my stock dash with a Dakota digital for the GN about a month ago and all was running fine. IDK if this could be related? Any help from all your expertise and knowledge would be a huge help so I don’t start going down a rabbit hole.
