Hesitation when turning right
#1
![Default](/forum/images/icons/icon1.gif)
11 XK NA has a bad hesitation when turning right onto another street when I am at half throttle or more, first 10 feet it takes off like a bullet and then it is like the fuel is cutoff. Will have no throttle response for about 1-2 seconds and then it takes off again. Does not matter what driving mode I am in, same thing. Though it is slightly better in sport mode.
Took to dealer and they say the firmware is up to date and they could not find any problems. Turning left is never an issue.

The FULL shut-off of Traction Control, a ten second hold of the TRAC button. Yes, that'd for sure let that problem known.

The other way I was on a track and trying to disengage the Traction Control completely but holding Trac DSC did not work for me, I tried to press it for longer and shorter, from Trac DSC activated and deactivate state, nothing worked.
Does that only work in XKR? I've got 2010 XK 5.0
This babysitting was really annoying coming out of corners and when drifting.

Try using SDD, TorquePro or similar to monitor the fuel rail pressure.
The fuel tank is of the "saddle" design, straddles the drive shaft, etc.
Mechanical fuel pump is in the right lobe/pocket, jet pump is in the left.
Right turns cause fuel migration to the left and vice versa.
If there is a problem with the jet pump, fuel can be isolated in that lobe.
The defect becomes noticable on right turns.
Fuel level on the instrument cluster is average of two senders in the tank.
If left lobe is full and right lobe (with mechanical pump) is empty, about 1/4 full is reported to the IC.
Let us know what you find.
