VR6 acceleration problem??

[golfaki]

Hi all,

As title reads, it's as if something is holdin it back and wont freely rev.

Where to start looking? leads ? plugs? Air flow meter ?

Have a MK4 therefore very new to the MK3 world (recently purchased)....

Appreciate any help as usual.

Cheers!

Coilpack / Spark plugs / Leads, in any order. I had to replace all three on my VR6 and now its runs magnificently.

Any recomendation as to where to purchase?

Repco ? Supr cheap ? Or even vw themselves??

Plugs you can get from supercheap, as for leads and coil packs go on ebay.uk or ebay.us as per the following links:

I have a set of these Formula power leads in my car and they're great, but also need some clips to hold in place as they are 10mm wide and cannot fit in the normal channels.

And here is my coilpack which is also great:

Hope that helps!

Could a dodgy fuel pump also cause this?

Correct, but I'd change the fuel filter first

Fuel filter definitely worth checking.

Fuel pump with a failing impeller and also pump relay can cause hesitation.

Another possibility is fuel pressure regulator with a leaky diaphragm. This can be checked by testing to see whether there is any fuel on the vacuum-line side of the FPR.

Leaky vacuum lines have also been know to cause problems on occasion.

With regards to the above leads, do you have to purchase the clips seperatley? from the same site ?

Anyone else had good experience with any other leads ??

I've got the same thing with mine although I think mine's a transmission problem at the moment.

It's been many things, and I'll fix it once but it comes back again. Prepare to live with it!! haha only joking.

I just used white polyurethane electrician clips which drilled into the plastic of the engine cover and that held them in place, keep mine they're a quad copper core lead as well and may interfere with your radio, not that I've ever had that though.

well thanks for all that, I will begin to play around this weekend and see what I can come up with.............

What Oil/filter are all you guys using? All locally purchased ??

Sorry about all the questions boys, just want to get it all upto scratch......

If there is anything else I should look to renew feel free to advise!

it sounds very like what was happening to my car.. does the temperature of the motor make any difference ie: does it only happen when car is cold or hot or always and also does the fuel level make any difference ie: does it only happen when fuel is at lower point of tank capacity or always.
the reason i ask is it only happened to my car when the car had warmed up but it also occured more intensely when the fuel was low. so mechanic thought it was to do with fuel system problem ie: filter, pump
but after trial and error, we ended up changing the leads and coilpack and car has run perfectly since.... hope this may help because i know when i had this problem it was one of the most frustrating things i have ever experienced

Nah, issue is constant no matter the fuel or temp. Will change the leads and plugs regardless, drop the oil and change the fuel filter & if it still ain't right look into the coil pack I guess ...

Thanks for everyones advise and direction.............

It turned out to be one faulty lead causing all that cough and splatter would you believe. I can now say I've been given an insight into the VR6 World.

Still going to give it a service and change plugs, filters etc however it does run a hell of alot better.

I would believe that unfortunately! It's crazy what such a small issue can do to the running quality of the car. Glad you got it sorted though dude!

From my personal experience, I'd advise you change all the leads anyway. This EXACT thing has happened to me, and while I replaced the lead that was faulty, it was only a matter of time before it started spluttering again. I'm about to change my spark plugs too - it's the last thing on the list of potential electrical problems. If my car keeps running badly, I'll have to look elsewhere, and that will get expensive!
