after I replaced mine I also replaced the o-rings, fuel filter, air filter, oil filter and oil, cabin air filter, MAF sensor the car was doing fine till started stalling and I took it to a Jag dealer they charged me $115 for a Com. Diagn. and said I got code p0340 which it was to replace the camshaft and crankshaft sensors I paid around $600 for the job two days later I had a code p0430 and they said it is my front Catalytic Converter they stated that the rear is faulty but I only get the code p0430 for the front one so total quote with both to be replaced and tech labor is $2.760 so I decided to to it myself . I have located the parts at $200 each but I am thinking in replacing the front cat only since it is the only code I get with my auto scanner.
Is ther anyone who can describe to me how to do this? and if any pics are attached it'll be much appreciated

 

All that just to change a spark plug.........smh

 

Hi everybody,

The floor carpet from the passenger side of my X-type is wet i noticed this and it is been going on for a while and dry out by itself but it comes back, It is coming from the buttom

Anyone had this problem? why it is wet? again passenger side floor, wet is coming from the buttom

 

Could be the climate system is leaking/excess condensation or the pollen filter housing has water in it.

 

Thanks man I think you are right because i had the same problem with the Dodge that I had but in this 04 X type 3.0 that I have no idea where to look under the car so can you elaborate on that I mean what I have to do to make it go away

 

What kind of spark plugs does everybody use? OEM? or something like E3. I just watched horsepower TV and they did a dyno test that showed more horsepower and better fuel economy using E3s.

 

After doing a little research it looks like the E3s were unreliable so i bought Bosch Platinum 4+

 

I guess OEM spark plugs are the best choice.

 

Alright, I diving into changing the plugs on my 2003 x-type. I think I've done all my homework and am using the Victor Reinz gaskets as some you have. Got my spark plugs gapped and ready to get my hands dirty.

 

Good luck! im doing mine soon

 

quick question! obviously i need the spark plugs if im gonna change them but what else do i need??? i heard i also need a new intake gasket manifold. true?? or what do i need exactly as far as parts?

 

Thank you so much for all of the information. I just replaced my spark plugs and gaskets this morning. I would have no idea what to do if it wasnt for this FAQ. It feels good to do it yourself.

 

Heres the comparison between the stock plugs with 111,000 miles on them and the new bosch 4s

 

Outstanding post great pictures .I'm new to the forum and I luv it here, so much info.
Thanks again

 

Hey I truly appreciate your post. I started to replace the PCV Valve because was leaking and I found the manifold and brake booster hose were leaky as well that was why I had idle problems anyways I just replaced the spark plugs but I got at the dealership a set of upper and lower gaskets for the manifold but I see only the ones on the picture... the oval ones, the smaller ones has a small elongation by the middle and I dont know where this ones goes. Can you please provide advise on this since you stated upper and lower which ones are upper and lower? and where they are located? Thanks, I greatly appreciate yor help.

 

Here you go, this thread talks about the lower ones...

Followed these instructions, SUPER helpful. Found insulation on wires on backside coils brittle and coming off. Temporary fix on that, car still had #4 cylinder misfire, swapped coil to cylinder #2, problem followed. Purchased one coil and replaced. New plugs, one new coil and holy crap what a difference performance wise! Love this forum!!!

 

Much thanks to this write up. It helped significantly.

Here are my plugs at over 156K. Glad I changed them. If it wasn't for the the broken plastic piece of brake booster vacuum hose going down into the intake, I would have likely waited longer.

 

Great info and pics i always set plugs to min setting so as to let them wear to max

 

Great thread and the pictures are thorough. Very thought out. I'm going to be change my plugs in the next couple days and will be using this for my guide. Thanks again and great post!
