Hi and thank you for your question.
The 2 highest probability problems that fit your description are either fuel starvation or mechanical issues.
The first thing we need to establish is that it is not a mechanical issue.
Have you done a compression test and if so, what do you have for compression on all 3 cylinders? If you haven't done a compression test yet, you need to do one right away before you do anything else. Diving into the fuel system will be a waste of your time if you have a mechanical problem.
Let me know where you are at in the diagnostic process and we can go from there.
Thanks Customer
