Maybe this is a bit obvious, I know i shouldnt have taken the cat out for a drive but i had to get the battery charged up, I noticed a burning rubber smell , Would that point to a vac leak?

Dam :( Just checked, Anyone can use my AA cover as long as its with the car, And that isnt the cat.

Hi Steve, I was with AA but i swapped that over to my other car i have to use whilst the jag is off road, Theres no Oil leaks as far as im aware.

Hi Joe, Thanks for the advice, Not sure if this will help diagnose but the car runs amazing when cold but as soon as it warms up it starts misfiring and limits me to 40mph, Its the V8 4.0 Petrol, I changed the fuel filter 2 days back hoping that would fix it but no :(

Hello, Some of you might know my cat has been misfiring, I have thrown allsorts of money at it now and its still misfiring, I have checked the sparks, they have all been changed by previous owner (they still look new), I have tried a coil test im not 100% sure if i have done this correctly, Its amazing how much a broken car can cause family problems, So im on here asking if anyone at all can come and help me fix this misfire or at least find the cause , I know its cheeky but i paid 1200 for the car and so far racked up 600 on bills, I really dont want to scrap it, I dont have alot of money but can supply endless cups of tea and bacon sandwiches :), Thank you.

Yes it is, Thank you very much :)

Hey, Its not too far but limited to 40mph could be a problem :(

Hello again, Some of you might know im trying to figure out whats causing the misfire i have on my V8 but have had no luck at all, I was wondering if theres anyone local to me that has the Jaguar IDS/SDD that can hook a laptop up to my V8 and finally get it sorted? , Im in Gloucester, Thanks 

Sounds good too me, I purchased a cheap code reader and it keeps coming back with 0 codes but i have a misfire, MY amber light flashes, So i put the code reader on after the drive and nothing shows up, This method your speaking about here sounds the best idea for me

Hi Joe its a petrol V8, I tried the reader and it shows 0 codes, Today i went out to look at the sparks and they are all brand new, As for the coils i took them out 1 by 1 last week and they all seem ok, Maybe i missed something

Sorted, Got my baby up and running, Now to the original problem i have, the MISFIRE :P

OK quick update, I had a friend who popped over lastnight to take a look at my situation, An hour later hes inside the boot!, He took out some of the rear seats with enough room to crawl into the boot and get things opened, That was the good news, The bad news now and more expense is my battery charger decided to die and now i have to buy another one, Its like someone does not want me to drive my car anymore haha, Anyway new charger coming today, Fingers crossed!

I really dont want to give up on the car, Its bugging me, Im not mechanically minded at all so i get stuck on the options i have been given by the members on here, I saw one about the starter motor?, Any diagrams or more basic instructions on how to do this would be great, Like a dummies guide, Thanks

I give up, The car is causing too much stress, I paid £1200 for it 2 weeks ago, since then spent just over £400 on it, Im going to sell it for silly money and call it a loss as i need a car 24/7 to be fair, Thanks for all your help.

If you have a spare battery, booster, or other 12 volt supply, you can connect it to the main supply under the bonnet (Fusebox) with the black lead to the bodywork. That will allow you to open the boot on the switch. PLEASE don't try and charge the battery at those terminals though. As soon as the boot is open, disconnect and charge the battery in the conventional way.

I have just popped the bonnet on my jag and cannot see a red wire near the fusebox, any help appreciated? 

Im actually close to getting rid of the car as i have had so many problems with it, Its becoming a money eater, If i can get this misfire sorted it may be saved

HI, Unplugging each coil one by one gives the same effect (slight engine noise change), It backfires when the engine has warmed up, It happens when idle too, But the car is perfect from a cold start until it warms up then it feels very sluggish then i get the flashing amber light, I have tried 2 code readers, the first one didnt work as it would not connect to the car so i purchased another one and it worked but showed no codes, I need a reader that can display pending codes i think.

I just ordered a charger that plugs into the cigarette lighter, Fingers crossed

I believe you can get trickle chargers that connect to the cigarette lighter from another car or a mains powered battery charger, which might provide enough power to open the boot. I don't know anything about them but might be worth a call to Halfords or if you have breakdown cover your provider might be able to help.

Thank you, I didnt even think of charging through the cigarette lighter, I found one for £19

Hello, I am so stupid, i cleaned the car out lastnight and left the key in the ignition overnight (on position) Now my battery is dead, As i understand the battery is in the boot? of a 1999 s type, Some idiot has removed the lock on the underlip of the boot so i cannot get into it, Is there any other way i can get into the boot?, My battery is completely dead so the boot lid switch dont even work.

Thanks

I had a misfire on my V6 due to water splashing up from a puddle, running down into the spark plug well and shorting out the HT to earth.

Anyway, if it will misfire at idle then you should be able to hear which bank it's on from the twin exhausts. You can then unplug each coil pack LT plug in turn (this is safe to do while the engine's running). When you unplug one and it has no effect on it running, that is it doesn't get worse, there's your misfiring cylinder.

Well , Spent this morning testing 1 by 1 , Now either im doing it wrong or theres no problems with coils, Next is to change all the sparks, If the problem is still there i will look for vac leaks.

Thanks for your help both. Ill try unplugging one by one and see what happens

Hello all, Got a quick question im hoping someone with some knowledge can help me on, Travelling on a main road the car starts to judder and RPM go right down and struggle to get past 50mph, Whilst this is happening the amber engine light flashes, I tried the odb scanner and it found 0 codes, I been reading around and sounds like it could be misfiring, My question is how do i check what cylinder is misfiring?

Thanks

Wow thanks for that write up, I'm going to give it a go when the kids are back at school, will post back with the result

Hi all, Got myself a s-type v8 and noticed the previous owner has super glued the front passenger window shut so I'm assuming he's a bit special and I have found a fault that needs fixing, Has anybody got a step by step dummy guide to replacing the regulator?

thanks
