Had my engine replaced last year in SD after it thru a rod . Was a remen motor. Runs fine but keep getting "Service engine soon". When I connect a scan tool I get 1 Fault and 0 pending. The scanner error message shows only N/A.. Tried 2 scanners but only get same results. Not sure what I am looking for or where it may be. Thinking the computer is going bad or maybe a lose connection show where. Local mechanic not sure what to do but start replacing parts which I do not want to go down that rat hole. Any suggestion that I might be able to pass on.
Thanks
