hey guys ,

I will try to make this long story as brief as possible haha! after almost two years off line .. heads removed new gasket , head job … new coil packs, spark plugs , engine oil gasket , injectors o rings and other seals/gaskets just fired up yesterday idling very ROUGH .
these are some of the codes im getting :

P0300 - Random misfire
P0301 - cylinder 1 misfire
P0303 - cylinder 3 misfire
P0305 - cylinder 5 misfire
P1313 - bank 1 misfire rate catalyst damage
P1314 - bank 2 misfire rate catalyst damage
P1316 - misfire excess emission

there are more too..
to get it started it was difficult it seem it wasn't getting fuel had to reset the enertia switch eventually figure that out ??
been reading on the IMT valves and fuel pressure regulator ….. how do I test those components and what else I should look for ???

help appreciated .

 

All of your specific misfire codes are on Bank 1 (for a 2005), which seems odd to have a Bank 2 catalyst damage code.

Misfire codes actually mean a low power impulse on the indicated cylinder. Given that the plugs,coil-packs and injector seals are reportedly new, a compression test on the bank one cylinders might be a good idea.

 

Gonna make me beg for these other codes?

Any chance the timing chain is not properly indexed on that bank? I think a compression test is a good idea. Improper valve timing would show up as low compression on the entire bank.

New coils? What brand? Some bargain brands are junk right out of the box.

 

yea guys ! actually looking more into the back of plenum where IMT valves are I found both of them bypassed no wiring connections at all going to the both valve ??? guess previous owner must have done that !
I won this car at a auction had the blown head gasket it barely ran .
so I went to the junk yard picked up both wiring plugs to both IMT valves .. I m planning to work on that tomorrow
as far t-chains I remembered following the procedure pretty close and yea the coil packs I got them from ebay !!
im going to run the OBD scanner again tonight to get a more accurate list I will post it as as possible

gracias-guys

I just pulled codes again these what I m getting now :

P1532 DTC definition not found please refer to the vehicle service manual
P1000 " "
P1549 " "

I think I was getting many more codes before improvement I think ???

 

All are defined in the workshop manual with causes - free download on this site.
Some/all also available from JagRepair.com - Jaguar Repair Information Resource

 

well !! got her running today sounds great after so much work and time !!!!!

I did replaced the gaskets on both IMT valves and wiring connectors plugs found one at junk yard and other one from Oreillys bad idea ! wrong plug tried to modify it still not making good connection planning on going looking for one back at junk yard tomorrow ,, also I got the ABS light on will that be causing any of those codes to keep showing up P1000, P1532 , P1549
I purchased an Autel Maxidiag MD808 PRO few weeks ago which I m trying to pull the abs codes ..
