Have u ever changed plugs before? Do u have any tools? You will need a spark plug socket, which is especially designed for this purpose, it will help to prevent damage to the plugs when u remove and install them. Also a ratchet wrench for the socket, and depending on your vehicle, u may need an extension. Purchase manufacturer recommended plugs (check your owners manual), you have to check the 'gap' of the plugs before installation, so u need a 'feeler gauge' or spark plug gap tool available at parts stores. Plug gap is set at the factory, but sometimes during shipping and handling they get banged around, so u have to check to make sure the gap is correct. 1st remove one plug at a time (so u don't mix up the order). To remove grab the spark plug wires, grab the 'boot' (the area of the wire that fits over the spark plug), push in, twist (does'nt matter which direction)and then pull out to remove. U don't want to yank on the wire, u can damage the the wire, so make sure u r twisting/pulling as close to the plug as possible. Once the wire is disconnected, remove the spark plug. Insert a new plug, by putting it in the socket, then by hand (not attached to your ratchet wrench yet) carefully screw it in (do not force it!). Once it's hand tightened, put the ratchet on and tighten snuggly (don't use brute force!) check the tightening instructions on the spark plug box. Reattach wire, proceed to the next plug. Aren't glad u don't have a 12 cylinder engine? How many miles on your Passat? If it's approaching 100k, u should also change your spark plug wires. Good Luck! Let me know how it goes. countrycurt0

How can i fix the missfire on a cylinder toyota corolla 2000 1.8ltr


First you need to retrieve codes from the Engine control module. You can buy a cheap code retriever at harbor freight and get the codes. After you get the codes, if it is P0301 it means cyl #1, P0302 = cyl #2, P0303=cyl 3 and P0304= cyl 4. For ex: if you got P0301 you should remove the ignition coil #1(near the front of the engine, where the pulley is) and change its position with the coil # 2. Also remove the spark plug #1 and change the position with the spark plug #4. Clear the codes and start and run the engine until the check engine light goes on. Check for codes and see if the code change for a different code. If it change the position observe which one is the change. If is P0304 you have a bad spark plug, If it is P0302 you have a bad coil. If it repeat P0301, you have either a low compression, bad injector/connector, bad intake gasket them you should continue your diagnostic. I hope this help you.

Does this car have spark plugs? Where are they?


What car? 4 cyl? 6 cyl? 8 cyl? 10 cyl? What year?
If it is a diesel, it has no spark plugs.
Most other BMWs have coil-over spark plugs. You remove the plastic cover on top of the engine and then unbolt and pull out the coils. The plugs are beneath the coils.

'86 honda accord 4 cyl...runs very rough as though missing on 1 cyl ...when removing plug wires 1 at a time each 1 removed makes engine run worse except for #1 cyl which when removed smooths engine out...


no, the plug is firing. But the timing is off. the plug is firing quite a bit before top dead center on that cylinder. The burning of the fuel mixture is occurring while that piston is on its way up and is slowing it down---dragging down the whole engine. i think you should change the distributor cap and rotor as cylinder one is firing at the same time as cylinder 2or 4. This indicates a possible carbon track in the distributor cap.

When the third spark plug wire is remove the engine rpm does not change, replace spark plugs and wires and yet no change. Also the rpm keeps fluctuating


sounds like the power pack is now good, follow the wire on the cyl. if its a 4 cyl. you might have to change the whole unit but maybe you can just replace half, you can get one at a junk yard cheap

Changed plugs and plug wires and now it wont start? i checked for spark off the distributer all 6 were good?


if your engine run before you changed anything,and you are talking about a 3.0 engine,
you have to be careful changing wires on this engine,
you need toonly change one wire at a time,the distributor cap on this engine is just stupid.
if you look under the cap you'll see that a wire on the one side of the cap actually has a contact that leads to the other side of the cap.
cly 5 cyl 6
cyl 3 cyl 4
cyl 1 cyl 2
front of engine

if your looking at distributor cap from front of engine,
two screws hold down cap.
look at the screw closest to the front,from that screw second hole to the left is #1.
firing order is 123456
#2 wire will be at that front screw on cap,keep installing wires counter clockwise.

Dead cylinders 2003 sebring


it sounds like you may have the wires on the wrong coil. It should be #1 on the #4 coil, and the #3 wire on the #2 coil. you probably have them backwards so 1 and 3 are firing on the exhaust stroke.
the firing order is 1-3-4-2.
they should be hooked like this.

Change spark plugs 2001 4 cyl hyundai sonata


You change One spark plug, and One wire at a time. Do you know where your timing belt is? If not, its on either the right or left side of the engine. There is a covor to the timing belt. You take the First plug that is closest to that belt. Then you work your way to the next closest all the way to the last one. Remember, you have to do ONE at a time.
