So I think my idle air valve on my 93 xjs is bad, and looking online I see that people suggest using a Lucas one, but I also see they are $200 each. I know there is a "alternate parts" listing for older v12s, but I haven't seen alternative parts listings for six's or facelifts. I did see one for $13, but it had bad reviews. There are several that I saw that looked exactly like them, but hard to tell from the pictures.

So, I'm assuming you have a 6-cylinder car, yes?

Google "DBC5727 Jaguar". There are a few out there including a couple new ones

Not aware of an 'alternate', personally, but i'm not versed on much 6-cylinder stuff

Cheers

Ok cool Ill look! Yes its a 6cyl facelift car.

Before you buy a new one, take the old one out and test it with boiling water.

I wish I had of done that as I ended up buying anothre one for nothing

what do you just put it in boiling water and it moves or something?

Yes. Use a heat gun or fill a cup with boiling water and dip the copper bulb into the water and you should see a valve slowly shut from the side inlet.

When it cools back down it should re-open.

Cool! Ill try that tomorrow!

Ah gotcha! I kinda wondered about that! Maybe Ill just pull it and try tearing it apart to see what I can see!

Ooops my bad!

Didn't read properly.

Presumed she was a 12. I am sure you would have seen the difference anyhoo
