Xb12r miss fire full throttle

[Andy841]

Hi after a bit of help please my 06 xb12r is missing when at full throttle can't get her above 90mph
It's had recent plugs and leads. Only thing I can think of is that the fuel pump has started to run all the time before starting instead of just priming the system (is this the pump in limp mode ?) which may explain the lack of power/missing at top end. Any help welcome cheers

So the fuel pump started priming all the time, not just for a few seconds while key is on and kill switch is flipped to run. And shortly after this started the full throttle issue started?
If I have it right it sounds like you need to pull the fuel pump, replace the screen, filter and repair any chaffed wires.
That's where I'd start since is sounds like the constant running pump is grounding out due to chaffed wiring.
Check out the fuel pump rebuild thread for a bit more guidance.
Good luck
