Hey Guys,

I've been having some engine misfire issues.

I changed out all the plugs, but found some oil in Cylinder 1 (This is the cylinder on the far passenger side under air intake manifold right?).

So I cleaned the oil out of the cylinder, changed the valve cover gasket, and i got the codes cleared at Autozone. The car ran pretty mint for 2 days, then it was like 5 degrees outside and had engine misfires like crazy.

Here's my new codes:

P1000- generic code?
P0300- Random cylinder misfire?
P0301- cylinder 1 misfire
P0302- cylinder 2
P0303- 3
P0304- 4
P1313- ???

My next step is going to probably be to change out some ignition coils----just wanted to check and see what you guys thought before I dropped ~$160.

I also want to replace my PCV valve and hose (to the updated version) and the Intake manifold gaskets at some point

 

Codes are all in JTIS, free download. You'll always regret not having it...

 

X-type code descriptions:

also, P1313 I think is due to excess misfires. When was the last time you did an ignition service? by ignition service I mean, coils and spark plugs.

Best of luck!

 

Hey Guys,

After doing some research on jaguarfourms, i was able to pinpoint the issue. I had a big leak at my IMT valves, and also maybe a small leak at my PCV hose. I put some duct tape over the leaks as a temporary fix....and it worked! the engine light shut off!

I did end up getting replacement OEM IMT gaskets and the newer PCV hose, and I replaced the parts today.
