So I have been driving with the derringer for about week now.... no issues what so ever until tonight... on my way home from work the idash displayed d-err code and also displayed fail to communicate. When I got to where I was going I checked all cables and connections... seemed to go back to normal no err code any more... when I put it in drive it said fail to communicate again and turned on engine light traction control light and said check parking brake... all while sending truck into reduced power.... I did diagnostic check and had codes for fuel rail pressure issues. I cleared codes and truck went back to normal along with derringer reading normal now.... while driving it threw all the same codes on the truck again and reduce engine output... I pulled over cleared codes and restarted truck checked connections again and has been running fine for last 10 miles....any thoughts what you think happened?
