Is it difficult to replace spark plugs in a Jaguar XJ8

I opened the hood and could not see exactly where to find the spark plugs. Also should I change the spark plug leads at the same time. The vehicle has 98k kilometres on the clock

Your car does not have plug leads so that will save you a job,the spark plugs are fairly easy to do tho.
Open the bonnet,either side of the engine at the top there are 2 black covers bolted to the top of your engine,bolted to those are 2 smaller covers,remove the 2 smaller covers which will reveal your ignition coils,remove the ciols and your spark plugs are there.
You will have to remove the air filter assembly tho on the right hand side which is easy enough,remove the bolts from pipe at the rear middle of engine,undo the clips which houses the filter and disconnect the engine breather pipe.Re assemble in reverse order,
N.B the spark plugs dont want tightening too tight..or too loose,when the plug nips up just give it a little nip again..GOOD LUCK

Initial start up the engine sounds like its running on 2 cylinders under powered intil the temp gauge reads normal ???? any body got the answer please


Cold starting misfires can often be caused by either tired high tension spark plug leads or ignition coil packs. If replacing leads, then replace with a full, new set. Coils can be changed individually, but it is often the case that if one has failed, then the others aren't far behind. Some cars have individual coil packs on each spark plug. Some cars have a single pack for all plugs and some have coil packs which may control two or more plugs.

To check for a misfire (ignition failure) follow these steps:

(Cold start) (Use a pair of insulated pliers)

1) Start the vehicle

2) When the vehicle starts misfiring, disconnect plug leads or coil pack connections one at a time. If the vehicle idles even more roughly, then that plug or pack should be considered fine.
Replug each connection before disconnecting the next one. Once you disconnect a plug lead or coil pack connection and find no difference in poor engine running, then you have likely found the offending cylinder. Check the spark plug condition, lead and/or coil condition and connections on that cylinder.

3) Replace components as necessary.

Fiat punto 2005 spark plug change


Hi Gerard, on a 1.28v Punto the plugs are on the back of the cylinder head tucked between the 4 inlet manifolds. The plug closest to the timing belt end (just next to the oil dipstick) is easy to find, the others are a bit obscured by the plastic housing that sheaths the injector wiring. Be careful pulling off the suppressor caps, they hang on quite tight so best use long nose pliers and NOT pull on the HT lead. Hope that helps. Andy

Is it possible to upset the timing by changing plugs and wires?


The timing in itself can't be affected by different leads and sparkplugs. The actual spark delivered in the cylinder differs when using other leads and sparkplugs than recommended by the Hyundai. This can go either way - better spark (high performance plugs) or less spark (lower quality materials).

Next to this leads can have leaks due to manufacturing faults. Simple way to test this is to open the hood when it's dark with running engine. Blue sparks are signs of leaks in the cables / caps.

My Isuzu Rodeo 95 doesnt have normal spark plugs-do I have to replace each cell?How often should these cells be changed?


hi this vehicle is the same as the Honda passport, just under a different name below is a link for the spark plug\'s you need, these are exactly the same vehicle under a different badge and they just are normal spark plugs, you might just be looking at the high tension leads that connect to the plugs, pull one off and you will see normal plugs, or check out images on line of your vehicle motor/engine...
hope this helps

Change spark plug wire


Buy the correct set of wires for your vehicle from an auto parts store, open your hood, remove and replace one wire at a time, with a new wire of the same lenght, from the box of new ones. Make sure you press the new wires firmly onto the spark plugs and distributor cap terminals until they snap on.

Need to change spark plugs. where are they located?


First locate the trim cover emblazoned with the "D-Tec 16V" logo. Remove the trim cover by removing the two bolts holding it down with a 5mm hex drive or allen wrench and gently lifting up. Underneath you will find the plugs. Remove the rubber boots without damaging them, then remove the plugs using a 5/8" spark plug socket. Adjust spark plug gap to .039" (thirty-nine thousandths of an inch). Coat threads lightly with anti-seize before re-installing them. Place a dab of dielectric tune-up grease inside each rubber boot at the end of the ignition wireset before re-installing. Replace trim cover, and you're done. You may also want to have a qualified technician perform a 3-part fuel induction service to your vehicle in addition to removing and replacing the spark plugs.

Changing spark plugs


look under hood..you will see wires coming from distributor cap on top into your motor..if its an 8 cylinder there will be 4 in the back and 4 in the front.6 cylinder-3 in front 3 in back.get a 5/16 spark plug wrench and socket.you will need extension to reach back ones.if you bought new wires from parts store it will be even easier to find where plugs are located because you can compare the ones you bought and easier find the wires under the hood.the wire gets fatter as it goes into the motor.grab the fat part firmly and pull it off.boom theres your spark plugs.use your spark plug socket(5/16) with extension/ratchet and turn the plug until it comes out.do not break the plug or it will not come out.when you put a new one in screw it hand tight then 1 crank tight with the ratchet.when you change your wires do them one at a time as to avoid switching the wires up.on top of the distributor cap(where the wires lead to) there will be numbers as to what wire is for what cylinder...change plugs/wires 1 at a time dont take off more than 1 wire at a time!hope this helped!
