Re: Just had my engine dyno'd and air fuel ratio checked
I would be wanting to read the pulses on a scope. The pulse timing
shows if everything electrical is working. Like below, if 5 are short
and the last one is long or no pulse or pulsing at the wrong time, etc.
At the same time I would be wanting to see the spark strength.
I would then be watching the leak down very closely when shut off to
eliminate dirt holding an injector open.
Didn't you have carb issues before putting the injection on with
flooding?
Your damage could have happened then.
