My x-type recently began stuttering and stalling when just under 1/4 of a tank of fuel. I has happened mostly when going up hills and the car won't start until I get on level ground. Diagnostic code P111 appeared to be the issue sighting an air to fuel problem. I am trying to find out what part in the car this relates to. Any suggestions?
This could come from your ECU, your gas line or who knows what. There are so many parts in jags its almost impossible to find the exact problem, which is why the **** at Jag have to decided to completely replace things instead of trying to fix them. Good Luck.

It sounds like some thing you have done if the fault started after the tune , did you check the gap on the new plugs, check the firing order as it may be messed up . 4 cylinder 1342 6 cylinder 153624 in direction of rotation.
Your fuel pump is not being supplied with adequate fuel pressure to deliver to your engine on an incline because of an obstruction in the fuel tank that changes from level to inclined. I have seen this on many vehicles over 15 years old mostly from rust, debris, and just plai bad gas. Have the fuel tank removed, cleaned and a new "Fuel Sock" (a sort of filter device made of a wire mesh) installed and the fuel lines blown out from front to rear. This should give you plenty of get up and go no matter what the angle your vehicle is in.
It sounds to me like a passing gear issue. Or even and Over Drive issue. Try this to find out. When you put the car in gear, instead of O/D, try regular drive. If you have a push button O/D then deactivate it. If you only have Drive, then try shifting into 3. Run the car up to the same speeds you were having problems with. If you don't have the issues with the higher RPM's then it is an Overdrive/Highway gear issue. If it still stutters, then it could be a fuel delivery issue. Good luck.
There are 3 potential issues with this;
A- Dirty injectors,
B- Tank Fuel pump is not putting out,
C- MAF Sensor is bad.
Does this happen more when you're on a hill?
Does this happen when your gas tank is 1/4 full?
What type of mileage do you have on vehicle?
the fuel pump and probably the fuel tank is going to need to be removed and inspected. it is very probable that the fuel pump hose in the module assembly has come apart or loose. i would suspect that you have just recently purchased the vehicle or had fuel system work performed. the reason it would work this way is because when the fuel is at a certain level then it sucks like a complete straw, but have you ever had a straw break and the soda got low? all of the sudden you start sucking air right? same thing. now unfortunately the tank does have to be "dropped" as opposed to finding an axcess cover. i trust this will be a stepping stone in the resolution of your problem. cheers!
had same problem with 00 dodge neon between half and quarter tank going up steep hills it would lose power and stumble,at quarter it would start to stumble and stall.fuel filter was completly blocked after changing fuel filter it would not stall,when gas tank was low fuel pressure would go down,changed fuel pump and it did it
