S-Type Check Engine Codes

S-Type Check Engine Codes
Hi, I'm a bit new here and was wondering if anyone could probably help diagnose what's wrong with my 2005 Jaguar S-type V6 (55k miles on it).
My check engine light is on. I took it to Midas and they read out the following codes:
P300
P301
P303
P305
P1313
P1316
P1111
The mechanic at that shop said I needed to replace my spark plugs. Although, when I drive my car I do not feel any misfiring at all. Plus, the car drives smoothly with no problems with performance at all.
Anyone might have a clue what these codes refer to? Would greatly appreciate it.

Could be as simple as changing the IMTs out!

Possibly plug and or a coil but doubtful at this point.

My check engine light just came on and I Firestone read the codes while getting an oil change. The codes were 171 and 174. The guy said the car was probably running a lean fuel mixture. I got back in the car and the light went off. I've noticed that the light will sometimes come on after adding fuel. Quirky, but the car runs great.

Klec, those codes are lean codes, could be anything from the air box lid not properly closed, to MAF sensor to vacuum leaks.
No one has yet to confirm if the MY 2006 and up have the green IMT O rings installed. Do the IMT check mentioned in the first thread in this post and report back.
Heres another link to codes P0171 and P0174:

Worth getting a cheap elm327 - about $15 on ebay.

So Rick, I checked the IMT O-Rings. They seem pretty clean to me. I did find some dirt, but seems normal to me. No oil found. (I did find a spider though if that counts..haha)

Salman as jagv8 described above (post #13), if you have an elm scanner that would be great.
Ok if the IMTs aren't leaking, it still doesn't mean that motor oil is not "pooling" in the lower IMT chamber. In the picture below, notice the oil in the lower chamber, upon removing the IMT valve alot more oil poured out. All that oil works itself into the passenger bank of engine, often causing misfires.
Another simple check is to remove the #1 sparkplug (front passenger plug), use a flashlight and see if there is oil saturating the sparkplug well and base of spark plug (not the firing tip itself), but inspect the tip should be whitish in color.
You are experiencing a misfire on the #1,3 and 5 cylinders, all on the passenger side of vehicle. Of course you cannot check #3 and #5 sparkplug wells without removing the intake manifold.
Did you name the spider?

Thanks guys for your help so far.
JagV8, just purchased it on ebay. Will be here next week. Glad you reccomended it since it might come in handy on the future too.
And Rick, I'll look into what you recommended too.
Never realised that trying to fix the problem would be like trying to solve some murder mystery..haha
Thankfully it's Columbus day on Monday. That means I have time off to do some "sleuthing" during the daylight...
In the meantime, hope you two have a great weekend.

One last thingy I can think of, check this "camshaft vent tube" from valve cover to the intake, be cautious though it may be somewhat brittle. I do recall long ago that another member had "bumped" the tube on the valve cover which caused a misfiring or vacuum leak (I cannot recall which).
The murder mystery solving is part of the fun!
BTW we (the kiddies and wifey) are planning to have a tremendous weekend as usual!!! Thanks for the "great weekend" wishes!
You hadn't mentioned what did you name the spider, we name all of ours "Charlotte".
