Hello all, it has been awhile. Had my check engine light come on so took it to get it read and it is a cylinder 1 missfire, now Im not sure which one is cylinder 1. I was told to check the wires and coils but I don't know which ones to check, so if anyone can help me outi would be very greatful, thank you

I guess it would help if i told you what car it is huh. Its a 2000 s-type v-6

 

Here you go,

In either case 1 is at the front left viewed facing the engine bay from in front of the vehicle.

 

You will find out but really consider changing all coils/plugs and valve cover gaskets. You have a pretty old car and they are wear items. Also the V-6 has several well known problems but they are cheap to fix. It's just better to do all the repairs at once.

Be sure to read the FAQs for that era & engine to save you a lot of pain!

 

Yea I was thinking about replacing them all anyway, I'll take a look at the FAQ thanks guys

 

Just a reminder, any OEM parts that are needed, give Nalley Jaguar in Atlanta a call. Free shipping with oreders over $75.00 and a 15% forum member discount. I have used them and other members too, nothing but grand reviews!

As club mentioned, consider vacuum lines, rubber elbow, intake seals (upper and lower), IMT O-ring (if applicable) etc....

 

I would also consider running some fuel injection cleaner like Techron through your fuel system. I had a low speed stumble which trigger the CEL while driving my Audi and the Techron did the trick.

 

Which ones are the valve cover gaskets, is out the same as the intake manifold gaskets? I have never really done much with this car so dont know much about it

 

One other question, I can't get new intake manifold gaskets for a few days (nobody around here has them in stock) would I be able to reuse the old ones for a few days our do they have to be replaced every time you take off the manifold?

 

Oh boy......

There are 2 valve covers, one on each side of the motor. Look where you would add motor oil into the engine after removing the oil cap (also known as the 710 cap).

The manifold gaskets, there are 2 LOWER intake manifold gasket and 6 UPPER intake gaskets for your model year vehicle. Both the UPPER and LOWER gaskets are located under the big silver thingy right on top the motor, in between the 2 valve covers.

Are you experienced in mechcanics?



This is debatable, some will say yes and some will say no. On a vehicle thats your age I WOULD! I would also have the valve cover gaskets on hand as well, you can always return them if there are no signs of leakage as mentioned prior.

Any of the BIG box auto parts stores should have the gaskets in stock, I would check around more.

 

Job finished and is running smooth now, engine light it's still on, is there a way to clear it

 

If it's fixed it will self-clear in 3 warm-ups.

Or disconnect battery for a couple of mins - but the risk with this is that you haven't fixed the real fault and end up with a car that can't flag codes but is not working properly.

 

Well the check engine light was off when I started it up this morning so I guess I did it right huh

 

Out of curiousity, what all did you end up replacing?

 

Ditto??

 

I did all spark plugs and could and lower intake gaskets.
