Good morning,

New member and new Jag own here. I am having an issue with my recently acquired XJ6, and I'm hoping the collective mind here can help me troubleshoot. Bought the car as a 'starts and dies' car with undiagnosed problems. Bought a new battery for it and was able to get it to start and mostly function, with the exception of the smoke when driving. When sitting in park, there's a small amount of smoke and fuel that come from the exhaust; but under load there's huge clouds that are left behind without much power. Only thing I've done so far is swap out the coolant temperature sensor, and cleaned of the distributor cap as best as possible and checked all of the injector and misc. other plugs to make sure there is no excessive corrosion. Can anyone offer any advice as to what I should troubleshoot next?

 

You have posted this question on the wrong forum - your car is known by its factory model code: XJ40. Yes, the badge on your car may say XJ6, but this forum is for the 6 cylinder XJ to 1987 and the V12 to 1992. Entirely different cars.

You want to post on the XJ40 forum page.

 

Thanks for that. I've been confused what this car is classified as, but was able to find it after this post!
