have you got any fault codes out of the system? the normal cause of poor running and misfires are the on plug coils. the cat system will report a a misfire to the powertrain control module and that will flag a fault code for a cat problem. check the resistance of the spark plugs because if they are too low they can damage the coils and spike the powertrain control module.we used to change 6 plugs and coils for this very problem, very expensive. the lambda sensors are also troublesome, bank a easy, bank b, good luck. change the plugs and use jag recomended. the fault codes are the key to sorting it out

VVTS is valve timing control. You need to have it diagnosed by a professional. Sorry

The heater is controlled by a 'variable solenoid water valve' that is controlled via the Air-conditioning module. These valves are prone to failure after a few years service. Another cause is if you have refilled the cooling system, the heater matrix sometimes airlocks, this can be overcome by bleeding the hose at high level by the heater hose in the engine bay. Good luck -hope this helps

IT MIGHT BE A RELAY GONE

Hi. On the left had side of the car, in the foot well, at the front about 4 inches up from the floor there will be a small round red button that easily pushes in. It's near the door. There will be either a hole slightly bigger than your finger or a small cover over it. If it clicks when you push it, it has been activated but this normally only happens when there has been an impact of some type as it's an emergency cut of. Hope this helps.

some cars will not run on certain spark plugs. ie my chev will not run on ngk plugs but ac delco only.check that first. or one or more coil packs faulty.

Check the obvious first. Is the fluid in the transmission at the correct level and the correct type for the car? Does it smell burnt ? Move on to the mechanicals. Is the linkage that controls the transmission operating? On to the electricals. Do all the connections to the transmission seem intact? Any missing connections? Burnt wires? If all the above appear to be correct then the trouble lies inside the transmission.

Hey Parnell, chances are the fault could lie with the fuses or with the body control module, I don't have a lot of experience with this model Jag so start with the fuses, if memory serves, there are two fuse panels, one under the bonnet and the other above the drivers knees inside the car, check them electrically with a test probe, looking at them is not enough. Replace any that are blown. If they blow again, seek the help of a qualified professional. If the issue is with the body control module, dont mess with it, have it repaired by a qualified professional. Check the lights switch and the interior light switch as well, if they are both on the same control ( interior lights and dash lamp dimmer) check it to ensure it is switching correctly. You may find that the dash lights and the external parking lamps may not be working as they are connected in some models so go the fuses first. If all else fails, try your local library for a copy of the wiring diagram or search it out online, this will tell you what and where the lights are connected and how they are switched. You can then backtrack each circuit to locate the issue. Again, if it looks like the issue is in the body control module, dont mess with it, that technology needs very specialist equipment and training..

On cold start up the computer is not looking at the air fuel mixture, only when it gets info from the ECT it then adjust the mixture. You have an exhaust leak under the hood somewhere. You may have the heater blowing at the same time bringing outside air in. This air has traces of the rich burning exhaust from the cold start up. Try turning the heater off until it is warmed up.

Explain rear indicator?

you know the easy-es way to do this is disconnect the battery + connection on the battery in the trunk then open the front hood & the the high been bulb from center in the back of your light pule it out by turning it the you will have a kind of big howl to rich the small bulb to take it out but it is too small for you to put your hand what you can do is to by water house open the water & put the house in the front light & feel it with water then the small bulb it is coming up flooding or even can come of the way you put water the same way come out with water it is songs crays but it should work. try it you wont loos any thing i hope the is help to you

If you know how, pull the radio and see if it has a seperate fuse on the back, not sure if yours has it or not, some do. My radio had to be replaced where the logic board inside the radio went band and would not turn off or on, gd luck with it hope this helped

Take the seat out and clean the inside of the tracks also check for broken cable or gears on each side.

good posibility is brake light switch. this sits up behind your brake pedal. if you can move gear shifter with key just in between off and acc put shifter in position just between drive and neutral or park and reverse see if you can get it into gear from there if so that is most likely issue

Nick, Based on the info it sounds like a possible blown head gasket, but lets be optimistic and seek some less expensive possibilities - perhaps it is a simple hose leak and the low coolant level is causing the problem... Source the leak.

that fault code relates to a internal component failure inside the gearbox, or a wiring problem from the powertrain controle module to the gearbox, it all depends on the gearbox that is fitted. if the gearbox has a plastic sump pan the controle module is part of the gearbox, the shift solenoid moves a valve inside the gearbox to direct fluid pressure to the relevant servos to control gearchanges e.t.c.does the car still drive?

Remove what?

check if the input side of the fuel pump has a restriction . a perished rubber hose can be a problem , the pump should be able reach a pressure 35 psi + and a flow of a quart every 30 seconds at this pressure.
