Cough/Splutter

[Mat]

Sorry if this is a daft question, but I'm hoping someone can confirm my suspisions.

On Friday I went to have a compression test before fitting the catch tank. Whilst the plug were out it made sense to change them all. (Spark Plugs)... Went out Friday night, everything was fine.

Saturday morning, pops out, 3 miles from home, bang. Coil Pack went. So replaced the knackered coil.

Last night (and this morning), when under full throttle and from around 2,750-3,000rpm and upwards, the car feels like its mis-firing. Can here it through the exhast and also feel it within the car itself.

Would this be a "symptom" as I've only replace the one coil pack and the others are "weaker"?

Hopefully will be getting some Bolt Down ones when they have em in stock. Does anyone have a part number for the bolt down ones?

bump

could be coil packs yes.. often they go @ same time
are the plugs fitted the right ones?

 

[M87NER]

part number for bolt down coils are 06B 905 115E

yeah, they're all right....

I wondered if it was a sign of having "weaker" plugs....

Cheers fella....

more money to spend

This rate I wont be able to afford big brakes

also need 2 rear tyres

 

[Mat]

sorry to be an arse, do you have a GSF part number? their site doesn't recognise that one!!!!

I had this on mine from what you describe, sounds like machine gun fire when the revs get about 2/3k, mine turned out to be the plugs after numerours swapping of coil packs, i'd make sure you've got the right plugs first and go from there.

 

[Mat]

they are definately the right plugs. the car was working fine between replacing the plugs and having a coil pack go...

 

[Cupra20]

definately a coilpack then i'd say, will just be trial and error process as to which one it is, unless you've got vagcom not sure if it tells you which one has gone but might give you a code for a misfire on the faulty bank.

What plugs did you put in there mat? And what did you gap them to?

 

[Mat]

what do you mean, "what did i gap them to?"

Just put a standard plug back in

Silly boy . They need to be gapped properly mat, i always set mine to .7 when i had mine. Surely you've heard of setting the plug gaps before mate?

 

[Mat]

nope.... we just plugged em in and off we went! could that be the issue?

How do you "GAP" them?

 

[Myki da Pyki]

Yes its highly likely to be a problem if there not gapped right mate.

Need to get a "feeler gauge" to set the gap correctly, like i said i always set mine to .7 when i had mine, but some would set it at .8 aswel.

The feeler gauge has loads of bits on so once you get the one you want out stick it between the tip of the plug and the post (only way to describe it lol) and tap the end of the plug gently with something to close the gap. Do this on all the plugs making sure they are all exactly the same or you'l end up with a missfire anyway lol

 

[Mat]

so whacking the top of the plugs to make sure they're in correct wasn't the best idea?

how do you "gap" bolt down ones then?

So, if I'm reading your post right, I need to go out to the car (after work) and pull each plug out a tiny bit?

 

[Mat]

just re-read, do you mean the metal part of the plug that goes in the engine????

God I'm sh1t at this car ownership malarky

 

[sparkie1984]

you have to adjust the depth of the electrode on them mate with a feeler guage to measure the gap

some do come preset though, i bought some from gsf that were

No the bit you gota work on is the other end of the plug lol, the bit you can see is only for the coilpack connection. Need to take them back out im afraid mat!!

Electrode, thats the word i was looking for lol
