    hello,

    Sometimes on my 2005 Detroit S60 on tenth gear my engine chokes/bogs down and goes from 13-14rpm to 10-11.

    I recently installed a full title exhaust manifold, already checked air filter.

    What should I be looking for fuel pump, ecm, injectors, something else ?

    Engines do not run that low. If you are trying to say 1300-1400 down to 1000-1100 then take a moment and type that out. It helps those few of us who have trouble with numbers like me. =)

    In top gear if you got all the way down to 1100, chances are that tractor will be bucking and wanting to stall completely. You would need to shift down at least two gears to recover the proper RPM range to keep it moving.

    I guess yeah. Still wondering what could be the reasons my engine is doing what it’s doing though and I should be looking for perhaps

    You ever find out what was causing the engine to "bog"? Mine just started doing the same thing.
