I think so, I found quite a bit of paint chips, which corresponds with the cool fuel paint issue.
Current update: Cleaned all injectors in my ultrasonic jewelry cleaner 30 min bath followed by a second in clean fuel injector cleaner. Then cleaned inside to confirm flow with fuel injector pulse/...

So, a summary of where I am today.
New Battery, New Sierra MAP Sensor, new Mercury MAT sensor. New Iridium spark plugs & New spark plug wires, from last year. Rebuilt cool fuel with new filters and Walbro pumps (low & hi). New box and a new top (pump cover with regulator) sent to me by mercury...
