I installed it thinking maybe I can catch a code before the main computer reset itself , but when it would die the codes where gone before the scII could scan them. Today We connected the IDS with the datalogger running took the truck for a 40 mile trip one way trying to repeat when it most often dies. got one hiccup on the return trip no codes burned another 10 gallons of fuel trying to repeat, nothing, Stopped to do some mothers day shopping and when I was pulling out of the parking lot it stumbled and almost died started running rough the data logger caught some codes I hope somebody can clarify them They are B1352 HEC Hybrid Electronic cluster U1261 HEC P0278-60 PCM cylinder 6? I think and P040-60 PCM has something to do with the EGR as I recall interesting thing is it has run rough since then. I should note in response to Cheezit the number 8 injector has not been contributing much for some time . I have been waiting to replace it thinking another would fail soon also since I have had multiple injector failures. Cheezit do you think a single injector would cause it to die randomly? and How can I throw codes for a Hybrid??? and would the egr and cylinder codes be a byproduct of the main issue or could they cause the problem? Sure would like to find the source of this problem thanks again for all who are trying to help
