vs missfiring problem

[aussielyn]

changed spark plugs, ignition leads, fuel filter fuel line, still shuttering problem badly, wat is going on here???

[Brett_jjj]

Check for any error codes Checking error codes VR/VS (Revised) Also see if you can borrow a coil from a mate and try it where each of your 3 go.(the cylinder numbers on them dont matter,they are all the same coils.)If you do find one is stuffed,its a good idea to replace all 3 at the same time.And try to use genuine ones.

[aussielyn]

wat u mean 3? there is more than 3 plug holes on coil

[Brett_jjj]

Is it V6,if it is there should be 3 coils,2 plug leads going to each single coil.

[aussielyn]

yea 3 coils six plugs, but i was told it not the coil doing this

[aussielyn]

i had spark plugs replaced by neighbour, since then it is even worse, b4 they were changed it wasnt missfiring as bad but now its so bad the whole car shutters,

[aussielyn]

2 leads going to each coil

Could be a dodgy spark plug in the new ones. Unplug one injector at a time, just pull the plug off, if you pull one of and the misfiring stop then you may have found your culprit, engine will still be rough though, since it will only be firing on 5 cylinders.

[aussielyn]

ok i go try now

[aussielyn]

ok lolllllllllllll i got a guy to do it and they all ok, cept his arm lol

[aussielyn]

new spark plugs and new leads so how can one b dodgy?

[Brett_jjj]

Test the coils like I said,they are a common cause of misfiring.Especially when they get old.They wear out just like anything else.If they have the cylinder numbers on them ,they are the original coils.New ones dont have the numbers.

[aussielyn]

how i test?

[aussielyn]

yes the coil has number on them but how do i kno what lead goes to what number or is it any lead? make sure number six is on spark plug six? how i kno this? hell im not mechanically minded lol

[Brett_jjj]

Borrow a coil from an engine thats running fine,You can check the coils with a multimeter,but Ive seen them show up ok on the multimeter and still cause misfiring.Mark the numbers on each of the leads (masking tape is good for this) ,and draw a diagram on paper of what number lead goes to which place on each coil.

[aussielyn]

there are numbers on the leads there numbers on coil its all mixed up but my question is wat is spark plug number 1, 2,3 and so on?

[aussielyn]

i just need to know what the fireing order is and i can rearange the plugs, if i start car with plugs in wrong place will it damage car?

[Brett_jjj]

Its the firing order for the engine which is 165432 for a VS V6.The leads have to go in this order.Cylinders 1,3,5 are behind the coils on the right side,1 being closest to the front of the engine,and cylinders 2,4,6 are on the left side,2 being at the front of the engine.Remember left and right are opposite when facing the engine from the front of the car compared to the normal drivers right side and passenger left side.

[aussielyn]

ok what side is 1 start from and starts at top or bottome, help?

[aussielyn]

can i take a foto of this and show u coz im hell confused.... the numbers on the three coils are differnt order to wat u sed

[acarmody]

Standing in front of the car looking at the engine. Passenger side is 1, 3, 5. Drivers side is 2, 4, 6.

[aussielyn]

this is too confusing for me, i dint understand, it seems my coil is different to wat yr saying

[acarmody]

Again standing in front of car looking at engine, coil pack left to right goes 6, 3, 2, 5, 4, 1.

[aussielyn]

so 1 starts from top of engine or bottom?

[Brett_jjj]

The numbers that are actually written on the coils wont be in the above order.They should be 3,6-left one,.The middle one should be 5,2, .And the right one should be 1,4.
