Running ruff.

[brainless]

I have a VN 3800 manual, began running poorly last Sunday, took the fuel filter off, blew it out and was full of rust/brown dirt, changed it, no difference to running, then the in tank fuel pump died, changed it, still running poor, changed starter motor, changed geny, blew out fuel line, still the same running ruff, picks up good on flat or down hill, but as soon as I begin an upward climb the car drops in power like it has dropped half a cylinder.
Any ideas?

If there was that much shit in the filter I'd be cleaning the injectors or getting new ones.

What about the ignition system? Might be a problem with that?

But definitely throw some injector cleaner or even consider getting the tank flushed and the lines blown...

Having dropped half a cylinder itll still run good as gold.. Had a really low compression in my old vn and it was perfect.
Clean your fuel/lines, Check your Injectors, Replace sparkplugs + leads, Clean/replace air filter.
If none of those help, Do a error check.
Checking your Computer for Faults (VN - VP)

if NONE of these help. Take it to mechanics.
