Long time ago when I was doing mobile repair I ran into a car that I couldn't figure out with my tote bag of tools. I spent 1-2 hours testing what I could and finally had to give up and refer the guy to a shop. I was pissed that I couldn't find the answer for him so I just charged him .5 hours for mine and his time. I was really happy when he called a few days later to tell me that the shop found his ecu was bad and asked if I would replace it for him. I wasn't as happy that he called me back to ask me to do the simple job, but more so that he found out what the issue was and told me about it. So I bet your mechanic would like to hear what the problem was/is because it will increase his knowledge and allow him to better diagnose this problem in the future if he encounters it again.
