sorry, I was not clear, yes EGR , hand forced vacuum (good EGR) makes RPM go to 400 RPM from normal; hot 800 and misfires vastly doing so. 400 shacks engine like wet dog does.
just closed the EGR main 100% and block the egr hose so EGR can not open again, as a test, even all week long test or years.
pump pressures good and wot too. 5psi rise. good.
rust i the tank allows rust tiny to walk past 40micron fuel filter and land on 6 ,10micron injectors screens (humans cant see)
and now injectors are partly clogged, and Injector balance test fails.
yes techron and pray;. yes.
misfire on good engines is bad spark or injectors dirty./
an injector shop pro that does injectors ,clean with reverse flow ,ultra sonic cleaner machines, to move the rust dust backwards out of injectors
yes pain , injectors can be, for sure any rust in the tank.
in the fuel loop , all.
