hey GUys i need some help, i have a 2005 gx that was running poorly and intermitently no start. the fuel pump terminals were all corroded and the pump was not working properly so that was replaced, then it would run fine but not great.and developed a stumble @ 900 through 1100RPMS. then it would smooth out. the whole boat would shake. the cap was corroded so the cap/rotor and plugs were replaced. with no change. then it stopped running entirely. diagnostics found that the coil output was very weak so the coil and wires were replaced. the boat now runs but the same stumble is still there.
i have verified the low and high fuel pressure, the spark is fine. the injectors are firing properly and i did a fuel injection cleaning on them. i did a cylinder balace test using the rinda scanner and all cylinders seem to react the same.
im stumped on this one.
any help is always appreciated
