FJH, you seldom walk away from an inquiry without asking "WHAT are you talking about". No matter how painfully random it is. Can the host build a pre-req questionnaire? Something for issue inquiries? An AI service writer with the four "W's" or flow chart? This sight is fairly well tweaked, you'd think it was possible. year make Model miles/hours Symptom Frequency active code present component repair history etc etc They could have a specific flow for each group heading.

fjh Posted October 20, 2017 Share Posted October 20, 2017 Ya would be nice however we got people that write service orders like that an it does nothing but piss me off. i don’t read minds I am however sometimes capable of reading what an engine is trying to say when it’s not feeling good if you give me proper info? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/51435-run-rough-and-pops-at-idle/#findComment-383034 Share on other sites More sharing options...
