For almost 2 years I have been trying to get my 1986 XJ6 tuned in so it will start easy and idle at 800rpm. When I got the car the pickup and ignition module were bad. I replaced both of them and it runs ok now but if I set the timing correctly it is near impossible to start. I also have to have the idle set at 950rpm so in gear with the A/C on it doesn't stall. I checked the compression and all cylinders are good. I have put around 8,000 miles on it since I have had it and my gas mileage is almost 16mpgs. I had a little preignition (spark knock) but switched to 93 octane and that went away.

Any advice as to what I should check would help me greatly because I'm trying to convince my wife that we need an XJS convertible too but if I can't fix the Jaguar we have now and make it so she can drive it than the XJS is probably out of the question.

Thank you
