UK-POLOS.NET - THE VW Polo Forum

Hello guys.

Since fitting my coilovers a little under a year ago, i've noticed that my HT leads always seem to be never fully sunk into there slot. It seems that when i'm driving that general bumps cause the leads to jump out of position, which causes my engine not to spark correctly (have a lurching affect when i accelerate)

Does anyone else have this problem or noticed it and have a solution???

Thanks, Mat

This was the same thing that happened to you when we we're driving back from the VW festival on sunday right? not sure how to help but someone will no doubt.

one of mine seems to half pop off every now and again, it's pretty annoying but i just always give them a firm thump on whenever i'm checking my oil or water

I had this same problem found out a spark plug was loose think it was 2nd cylinder ,i had the car a year and hadnt changed them, done them now and the leads due to the leads being burnt at the coil pack end, all fine now,

could be a loose plug as above, maybe re-new them all and consider a new lead too?

not sure what is causing the issue

Take a read of this.
Best part was a VW quote

the problem is that cause you havent got an engine cover on, this is why your leads are coming off. it stops them moving...

lol this is the funniest thing i've heard, made my day

Cheers guys.

I'm gonna order a new set of plugs and leads..........hopefully that will solve the whole problem.

Will let you know how i get on!!!!

Well as some of you said, the plugs were loose.

I drove down to Kent on Monday and it was such a bind having no acceleration. Decided to bite the bullet and just get a full set of plugs and leads.

So i then go round to my ex girl friends house, who's dad is a dab hand at mechanical stuff. As he was replacing them, he talked me through some stuff which was well useful. He told me 3 of the plugs were too loose. Because they're not tight enough, the pressures which get built up when the cylinder moves are escaping slightly causing the leads to pop up. Funnily enough aswell, the 1 spark plug that was in properly was in the best condition.

So there you go guys. If you are experiencing lurching when accelerating or you notice your leads popping up........check your plugs.

Good Tip

Be careful you dont overtighten them tho, cos you can feck the thread up

It's also a good idea to put a tiny smear of copper grease on the threads too, to make them easy to remove come check up time.

How much were the new plugs and leads? I think mine is starting to do this.

It sometimes hard to start up, it splutters and does all sorts sometime. My mate pushed one of the leads/spark plugs in and it was fine, but it has started doing it again.

So i think my problem is the spark plugs/leads. As its new, id rather just replace the whole lot, just to eliminate that possiblity

Cheers

There should be a topic posted in the Vag-parts sections of the forum.

Think it worked out to be about £60 for the lot.

HTH.
