Thanks for the suggestion! I threw a bottle of octane booster in there but unfortunately there was no change.
I'm thinking it has to be an electrical because all of my fuel trims are just showing dash's there is no readings from them at all.

This guy seems to of had almost the same issue except he was receiving a P0174 which I am not: The codes are in: P0300 thru P0308, P0174, P1316. When feeling around the charge air cooler ducts where his problem was at I cannot feel any suction problems and they look in place.

Did you ever figure out the problem. I finally got the new engine in my XKR this week and have exactly the same codes and problems. Idles like a pig, no real get up and go etc. My spark plugs are all new, I swapped my coils back to the known good ones from the original engine, it has 2 brand new fuel pumps, new battery and new alternator too.
My biggest fear is that I somehow skipped a tooth on the timing when I was replacing the tensioners.. Would this cause the same faults? Does anyone know how this would manifest itself if I did a compression test (eg. low compression on one bank)
I just purchased an Electronic Ignition Spark Tester and will be checking each coil tomorrow just in case I have one or two bad ones causing the issues even though I am showing misfires on all cylinders on both OBD testers..
Thanks
Dan.

I tested each individual coil today and found one that seemed a little lacking in energy so I replaced it.
The car runs a little better but far from right. After resetting the codes I went for a drive and after about 20minutes I had the following faults pending.. P0300, P1316 and P0174.
I identified a couple of suspect vacuum pipes which I'll get on with tomorrow after I have pulled the cam covers and verified the timing.

Well, to wrap my saga up - it was valve timing!
The RHS Exhaust cam was one tooth off.. I have absolutely no idea how this happened. I put new tensioners in there while the engine was out of the car. I can only assume that I was not careful enough when I used the zip-tie method as I cannot see any way that it would jump a tooth under normal situations with the new tensioners.
As soon as I took off the cam cover it was very obvious. I am soooo lucky that it did not turn my newly rebuilt motor into a grenade!
Anyway, just stopped home to post this and now I'm heading out again to enjoy the upgraded supercharger pulleys and the transmission solenoids... and also to ponder what I can have disturbed during fuel pump replacement that is now giving me 'suspension fault' on the dash..
Happy Jaguaring.

You did pull the orange pin out of the tensioner. It's hard to believe the zip tie allowed it to go back one tooth off unless it was off to begin with.
Anyway, here is an example of why it's important to check cam alignment after installation. We all get in a hurry sometimes, and I'm pleased to hear you have it sorted.

[QUOTE=seawind;1234653]On the driver side of the throttle body? There is a black and white plug on the driver side which I disconnected and inspected but they are dry as a bone. There are also some plugs almost right behind the throttle body that are a lot harder to get to... are you talking about them?

When feeling around the charge air cooler ducts it would be really hard to feel for any suction problems (you would most likely hear a vacuum leak in that area though). In my opinion, i think it is possible that you disturbed the charge air cooler seals with the pressure washer and caused one of the seals to leak. Just remove the seal and plates to see if the seal slipped out, also see if your sealing plates need to be upgraded, as they should have a groove that holds the backside of the seal. I had a vacuum leak that flashed every code you mentioned and one of the seals having a small cut was the problem. (It only take about 30min to remove the plates and seals, so it worth checking before looking elsewhere)

Hey guys sorry for the late response. My problem was the same problem that I had found here: The codes are in: P0300 thru P0308, P0174, P1316. Even after the parts were replaced there was still a small leak so my mechanic used some weather sealant and I have had no problems since.
