The engine is not knocking. Didn't think about just plugging in the new one....
Too late, the old one is already in the trash.
Consistent p0327 P1000 after clearing.
I'll finish assembling it and test drive it today and report back.

 

Ok lots more issues.... new thread time.

 

You mentioned the rpms were only about 2500. With fly by wire, this is usually what the engine will rev when out of gear. Rolling in gear on the road, it should turn about 6,000.

 

Yeah and under load it only pulls to 2500 then the ses starts flashing and running like absolute ****

 

If that's the MIL then it's saying misfires so bad they're cat-damaging then and there.

 

Yeah, Code stored after that is P1316 or whatever the cat killer is.
And why is it doing it?

I have to reload my scanner onto my laptop to get live data stream back to check the fuel trims....

 

Then you can check if it's a leak and if so go hunting for it.

 

I have done a smoke test, as well as test with brake cleaner. no indications of a break in the intake tract after the MAF.

 

But what do the trims show?

Going to continue this line of troubleshooting/repair on this thread.

 

Ditto on the fuel trims for me Toybreaker. Lucky for me most all of my rough running issues on our 2 Jags thru the years were resolved with the replacement of one or more ignition coils, zip tieing the connectors here and there, (mainly the throttle motor). and re-timing and associated repairs to the exhaust cam left bank.
A quick check thru the Jag engine stalling reference reminded me of the importance of having the right spark plugs. If the OHM is different, the PCM, ECM ECU whatever, won't read correctly. The other thing comes to mind is the sealing of the air boxes, since the flow thru dictates the fuel and spark delivery. Something else that seems to mess with peoples heads is the grounding of the battery to the engine block and particular sensors. I have seen grounds contribute more than their fair share of weirdness. Just because they crank over, might not mean good enough. Sorry If I am repeating what anybody else has already stated.

 

What kind of battery did you get???????

 

And what is your voltage on the TPS
