X-Type with manual transmission sometimes Jerks at 3000rpm, and at 1/4 tank

Hello,

I have a 2002 X-type 2.5 with a manual transmission and around 75k miles. Every now and then, maybe once a week or so the yellow light inside the rpm gauge comes on, the mileage display says cruise not available, and i cannot go above 3000rpm in any gear, the car will start to buck back and forth if i try to. Usually after a few minutes it will stop and the car will perform normal.

Also i have noticed now that when I have around a 1/4 tank of gas left and hit a hill, the car will start to jerk back and forth. I then fill it up with fuel and the car is fine.

The check engine light does not come on during this, so i cannot check the codes, Any idea what the problem could be?

Thanks for any response.

Regards,
Ryan

There will be codes stored as the MIL light did come on
Even if no MIL light comes on codes can still be stored as not all codes illuminate the MIL

The 03 X-Type I used to have developed the occasional jerk at low fuel levels like yours. The car uses 2 fuel pumps - 1 to supply the engine, and 1 to transfer fuel between the 2 sides of the saddle type fuel tank. I suspect your transfer pump has a problem. On my car, in addition to the jerk problem, my tank fuel level sending unit went bad. The dealer replaced the pump/sending unit assembly under warranty, and, that solved both problems.

The cruise not available light is most likely a leak from the pcv hose and/or the two seals at the back of the engine on the passenger side on the intake manifold. Check the hose at the front of the engine under the jaguar cover
