I was doing some more research and reading (in my Bosch Injection and Fuel Management book by Probst) and it mentions this:
Quote:
"For KE Systems, measure delivery at the return line from the system-pressure regulator. Measure where the flexible line meets the steel tubing. Disconnect the return line and attach a test hose.
You're measuring pump delivery at the return line instead of the input to the fuel distributor because fuel delivery is specified at system pressure, against the force of the system-pressure regulator, and would be different if measured at an open supply line."

Looks like I did it the wrong way a few months ago. I read it, but did it wrong anyways LOL. I just didn't think about it requiring force against the FPR. Live and learn!

Only thing is that it mentions testing it at the fuel return line at regulator, not where I tested it. I assume I should be OK where I tested it right since the distributor is new, there will be no restrictions there. |
I will redo the test -- Maybe its not the injectors then! (although they should be cleaned again now) Let's see what the fuel pump delivery test reveals now!
Since the car starts and idles perfectly, its just possible full load flow is hindered somewhere upstream (pumps or strainer), hence WOT power is lifeless and high end rpm gets a knock. Makes sense to me logically.
