2005 XJR Restricted performance
Guest
Posts: n/a
I have a 2005 XJR and recently installed a Mina Gallery free flowing intake. I had a couple of experiences where I was under full throttle acceleration and once I hit about 110 the yellow warning and "restricted performance" kicked in. I took it to my local dealer and paid to have the "fuel system maint" done and the codes read/checked. They cleaned everything and adjusted the fuel "trims" and had me back on the road.
Now the problem is worse! I can't get the car above 4k rpm under any kind of acceleration and the yellow warning restricted performance kicks in. And now there is a sound that accopmanies all this that sounds like a severe knock.
Any suggestions? I plan on removing the new intake just to see if that has any affect. I use premium fuel only.
