Tested fuel pressure before rail (43) at fuel rail (38) and stays there while running. Checked idle control TPS both seem to be fine.
I have replaced the fuel pressure regulator, cleaned all injectors and replaced all seals, plan to change all plugs in the a.M.
Question is what else may cause such a problem as this? I don't think it is pump or filter related because of the pressure reading from the test.
Can you help with this one?
