Hi Guys

Hope someone maybe be able to help me here, I have a Jag Xjs 3.6 1990.
The problem is that the idle is very slightly lumpy and at around 3500RPM its starts fart around and pop etc. When driving it holds back.

So far I have tested
Fuel presure Ok
Plugs changed
HT leads changed
Cap and rotor arm changed

Yet the problem is still here,,,,, However I have also noted that the seems to be running lean looking at the analsyer results from the last MOT 2 weeks ago.

CP @ 0.88 and HC @ 98ppm

I think this would explain my high engine temp!

Any help would be appreciated
