Emissions and idle
Hi everyone,
My 94 XJ81 is running but not as well as i would like. The idle is around 800rpm but not as smooth as I would expect. She went through Utah emissions after work but to me the idle HC values are still high. Assuming all emission tests in the US are the same way what value do you get for you V12's for the hydrocarbon levels at idle and 2000 rpm? I'm sure mine is still a lot higher than it should be. 2358 rpm is fine at 93 but idle is 805rpm and 191 for the HC level. Are my values normal or overly high, considering she has only just rolled over 83K miles? If they are high and my idle is a little rough, where should i be looking next? Thanks, Andy |
Another issue today, posted in the introduction Section but now the fuel gauge is playing up!

The XJ81 is rare and very desireable variant. If you don't get help on the idle/HC issue here, try our XJS forum - there's a lot of V12 expertise there. Graham |
