Great forum all, so far loving it, been reading a lot and have learned a lot too.

Currently bought a 2003 Gold Jag S-Type 3.0 with 115000 miles for 2500, it runs

and drives nice, however it does need some work to be in top shaped.

MIL is on with 1532,1647,1316,1549 and also shows misfires on cyl 1,2,3,4,5,6 which is weird cause it does run i use it everyday, but the symptoms are when i start the car Cold in the morning, while idling, it starts to shake and hesitate after its hot it runs beautiful.

any help or ideas or a place you can point me in, would be appreciated

 

Welcome to the forum gabyman97596,

I've copied this MIL question from your Intro for advice from the model experts.

thanks G

 

o2 sensors?

 

Welcome and check your battery, sounds like it might need replacing..
If you can access each cell on the battery, go to an auto parts store and get a hygrometer, then check them out. Could be one or more cells are weak.

 

First thing is to look up all the codes. Now, each must have a letter at the front so be sure to include it or you'll be very lost - same as we are as you left them out.

The codes PDF is in the stickies and also in JTIS, both free on here.

If they're all P codes then you have IMT faults and an O2 sensor fault so misfires are inevitable until those are fixed. See HowTos / JTIS.

 

Sounds like intake manifold gaskets are leaking.

 

Starts right up everytime but ill have the battery check. those are all P codes JAgv8. already ordered the Jtis program, just waiting to get home to play with the program and start trouble shooting. the misfires are pretty much on first morning start while idling..

 

Ok, so I bought manifold gaskets, spark plugs iridium, serpentine belt, air filter, oil and oil filter. I will be performing a tune up first to see how it performs afterwards.

Those this cars hate regular fuel ,87octane?

 

You might want to add valve cover gaskets to your list as well. For the little time that it takes to install them and spark plug well gaskets (come in same kit if you go aftermarket like FelPro) you'll thank yourself down the road.


Be careful with all the plastic vacuum lines as they tend to get (be) very brittle in this stage of their life span.




This may or may not help you out as well:

I order that as well too. Anything else i should be changing since im taking out all that?

 

yeah, those "so-called" quick-connects at the manifold (one front, one back) can be a real (bitter ex-wife!)


Actually, the nomenclature is correct, they are quick-to-connect - woe to he who attempts a disconnect, however!

 

Maybe not all but with 115k on your S Type again take a look here:
2003, 3.0, 90k "maintenance"

 

Jaguar specifies 91 octane, but there are lots of discussions in the Forum on octane in which some members report they have absolutely no issues using regular. BTW - in 2003 Jaguar called that gold color "Topaz". I have it too. Good luck and welcome to the Forum.

Thanks jumping, first time I fill it up was 93octane gas but wife was using the car and she was using regular, and I thought that may be causing issues as well. Haven done anything yet as I am waiting on the valve cover gaskets so probably next week ill start working on that. Thanks everybody so far this forum has been very helpful

 

Happy to help, gabyman. There are some true Jaguar experts and highly skilled mechanics on this Forum. My best advice is to search for answers to your questions using the search feature of the Forum (it's quite good), and heed the advice of the experts. Good luck!

 

So just finish putting everything back together. Valve cover gaskets, spark plugs, upper lower intake gasket, water pump, serpentine belt and oil changed.

heres what I found: spark plugs where original and they were horribly corroded, also lots of oil inside there. Intake air control valve sensor plug disconnected, brake booster vacuum line broken, my oh my what a job but manage to do everything on one day. Spent no more than 200 on parts and saved a couple of 100s on labor.

A good six pack of cold beers, father on the side, and job complete lol. No leaks, even the MIL hasnt come on yet.

lets see whats next

Looking forward from now on to fix up everything that happens.

 

Congrats job well done!
