Recently acquired a 2017 Challenger 750. Previous owner ran it low on oil so I had to do a top end. Starts and runs but it seems to be running very rich. There isn't too much information available for troubleshooting the EFI system. Air filter is new and I even tried running with it removed with no change. Some of the parts are relatively cheap, so I did replace the IAC and the MAF sensor. Could this be related to the TPS sensor or which direction should I head in next? There doesn't seem to be any adjustment on the TPS and I have read something about a WOT ECU reset but that didn't change anything.
Thanks in advance
