Thanks for all your help with my transmission failure. Took it Dana Point Ca. AAMCO and the car runs great!
Now I am getting intermittent restricted performance light, very rough idle, when I scanned for codes, these came up: 175, 172, 1316, 101, and numerous misfire codes, along with EVAP, O2 sensor, Fuel, Catalyst, and O2 Heater.
Hoping it is simple like a dirty MAF or bad Lambda sensor? Any thoughts.

 

I used to get 175 and 172 codes, which was remedied by moving up to 94 octane on my xkr, though I suspect that was because of my SC boost increase through a smaller pulley which doesn't really help you.

I believe 1316 is a MAF code, that would also explain the restricted performance and rough idle. Disconnecting, cleaning & reassembly might help, or a replacement altogether.

 

Check that the transmission mechanic hasn't deranged your O2 sensor cables, ie hooked the left cable to the right sensor, it is easily done, there was a post recently about it. I think they are the same colour, just to make life more difficult.

 

Cleaned the MAF and throttle throat, I found a small crack on the air intake support bracket!
New tank of Chevron premium and the Jaguar is again purring.
Thanks for everyone's help, I don't think you can own this type of car without the support of this forum.
