My 2L-TE is a bit low on power. It seems to run fine otherwise, just not quite as powerful as it used to be. I tested the injectors, and they all passed the leak test just fine. They also all open at right around 2200 psi. The spray pattern looks good on all four as well, compared to pics I've seen online.
However, the factory manual RM520E says, for the spray pattern test:
"(a) The injection nozzle should shudder at a certain pumping speed between 15 — 60 times (old nozzle) or 30— 60 times (new nozzle) per minute.
(b) Check the spray pattern during shuddering. If the spray pattern is not correct during shuddering, the nozzle must be replaced or cleaned."
I can't seem to figure out what the "certain pumping speed" is- and I can't get the injectors to shudder.
Does anyone have any experience testing these injectors? Is it critical to observe the proper shudder, or if everything else seems fine is the shuddering test not that important?
