Yes, weak coil was exactly what I suspected - hence I rushed and bought some - I went down an initial blind alley with the wrong cylinder as I didn't look properly at the two cylinder numbering options! I also possibly need to run it longer to see if I get any other codes. The problem is, as...

Thanks Jim, I purchased a smoke tester last week and of course the cone was too small for the maf inlet which resulted in an unsatisfactory bodge with a ploy bag and gaffa tape - but did get me as far as leaky throttle body seals - which are hopefully fixed. Looking for a better smoke cone...

Yes, I know it's a misfire - I started with plugs, coil and injector all OK - I'm expanding the search to see what else can cause it

Yes, well I had almost convinced myself I needed to drop the tank and look at the filter or pump or both - just trying to be sure

Fuel rail has temp sensor on one side and pressure sensor on the other (with a vacuum line) Fuel pump pressure is regulated by a fuel pump driver control module in the boot linked to the ECU fed by the pressure sensor - at least that is my schoolboy summary of what I've read It's not clear...

So looking at the two numbering options it's either - 3rd back on the drivers side or first at the front on the passenger side :) I pulled the coil and started it to work it out and it's Front left I've swapped coils around and compression tested but all looks good from that perspective - I'm...

Yes, totally agree, it is a little chicken and egg though as I don't know why the cats were removed. - did a misfire kill the cats causing them to be smashed out as a'cheapo fix' - were the cat's removed and programmed out when the sports exhaust was added ? Ultimately the cats have to be...

Interestingly I've just taken the RRS out for a run with my icarsoft in theory logging data in real-time but in actuality nothing got saved! So I plugged SDD in and looked at the snapshot data held against the P0305: Now as soon as the misfire count hits the magic threshold the code is thrown...

My XKR suffered from exactly that issue of a torrent of water leaking through the bonnet vents and getting under the coil pack covers

That may actually be an option, I was however a little nervous about changing the module as I have heard anecdotal stories of vehicle mileage being updated from instrument packs or ECU changes (paranoid me?)

Morning all, I’m still chasing a misfire on my ‘cheap’ 4.2 s/c RRS I’m slowly narrowing it down: Compression is good across all cylinders (both hot and cold) All coil packs are good Plugs are new 02 sensors are good Starting to suspect it’s fuel pressure related - subject to me getting a y...

Hi Mark, I’ve yet to roll my sleeves up, it does have coil packs - it has new spark plugs. I will do some coil pack checking and swapping. It’s. It not misfiring at all on idle. It does smell like it’s running very rich. I will hopefully be able to do some diagnosis this weekend. I will spray...

That is brilliant - Thanks Kev

Title says it all! I’ve managed to get a workshop manual for my ‘05 sport supercharged but my search and Google skills have failed me with respect to a parts catalogue - can anyone point me at a pdf - or the equivalent of JTIS (for jag parts)

I’m tracking down a misfire on 1 cylinder

Ok - I will give it a go with a little pre-soak and see how I get on

Morning all, I’m looking for recommendations for a slide hammer to use to remove the injectors on my 05 RRS 4.2 s/c. I’ve seen them advertised for around £65 with a slight bend to them. I was wondering what experience folks have had and whether the ‘bent’ version is what’s required for access...

Hmm ok so managed to CtlC/Ctrl V

As if I don't have enough projects, my defender 110 bulkhead replacement got paused due to winter and home extension delays, my Jag 3.8S full resto got paused to sort the defender, My XKR is running so I am pretending I can't hear the tick from the supercharger.... I purchased a new (for me)...

Sorry for the delay in responding and thanks for all the suggestions. I got diverted as our kitchen is being demolished… Re: the bulkhead, most of the removal work is done, inside is stripped, just got a few hours of removal to go, new one is in the garage all painted and dinitroled. I will...
