As if its Running on 3 - Vts HELP :(

15th March 2013, 21:56

Basically the night before fast show it decided like it wants to run on 3 cylinders

Checked plugs, they're all spot on, put another coil pack on and made no difference

Idle is fine but it has no power what so ever

It did it the other day briefly for a minute or so then stopped, but today 5 mins after setting off from work it did it again and hasn't stopped

It's also backfiring like no tomorrow too now

Something's wrong

15th March 2013, 22:18

Maybe an injector has gone?

Bit of a pain but I would get the top of the inlet off, pop the fuel rail off and turn it over a couple times to make sure all are squirting.

If one isn't swap it with another that is working so you can check it is an actual injector and not the wiring.

15th March 2013, 22:36

i once snapped a locking wheel nut key with the locking nut still on with a none road worthy wheel on 9pm night before ford fair. I was pretty gutted.
Just the way it goes sometimes.

15th March 2013, 22:42

shit aint it, tbh if i cant sort it within half an hour tomorrow morning im still gonna drive the cunt down there, if it dies a death it dies , ive had enough of it

15th March 2013, 22:50

also the idle is fine, surley if one of the injectors was dead it would idle shit wouldnt it?

15th March 2013, 22:58

Was the other coilpack you try definatley tested/working?

15th March 2013, 23:02

If it was an injector then it would just run lumpy and judder to about 3k rpm, then run fine

If the coilpacks been changed, then maybe the map sensor? Ali also didn't you have the loom spliced when having the engine fitted? If so then are all the connections and wires in the loom still in one piece?

It sucks when your car goes wrong just before a big day, my boost pipe fell off last year on the way to Trax

16th March 2013, 00:01

Check crank sensor plug aint loose

16th March 2013, 00:09

It can be many things you'll just have to do checks,

Not so bad its done it now better then doing on the way or once you got there

16th March 2013, 00:45

Fuck me are you joking?

You fancy torching our cars together? Mines getting sorned on Monday ;'(

Edit - if you need injectors give me a shout i have 12!!

No mate not atall

and yes! Lets

But shall do man!

20th March 2013, 22:32

right! over night before fast show it sorted it self out! drove there sat fine, drove back sunday fine, drove monday fine till monday night it started doing it again

left it over night drove to work fine and back, this morning did it again, but driving back was fine, then tonight it did it again!

it idles fine when its running on all 4! but when it startes running on 3 it'll idle fine but ever few mins the revs will drop, idle lumpy then idle fine again! its starting to really piss me off!

also it seems okay ish until 3k then it gets really noticeable and you can hear the exhaust note "pulsating" if that makes sense?

did a comp test on it today and it was 160ish across all 4, tried a brand new coilpack like said above and no difference, so can it be an intermittent injector fault ?

Check the wiring loom for the injectors in case there is a break in it.

21st March 2013, 11:49

Sounds exactly like my old VTS, there was a break in the injector loom.

Check it.

21st March 2013, 11:55

If its three cylinders it usually sounds like a 'subaru' is the only way to describe it. If it doesn't i doubt its running three cylinders maybe abit lump idle but not smooth on the drive.

Check the wiring to the lambda sensor also take out the lambda and check its all there and clean.

Check the injectors as stated above along with the crank sensor.

Do a reset on the ecu take battery off over night etc.

Good luck.

21st March 2013, 12:01

Mine was dude, was smooth to drive at times, until it started running on three, then it was as Ali is describing

its deffo running on 3 mate when it does it, its okay for one min on idle then goes really lump, and it is completley gutless to drive and you can just hear by the exhaust note it aint running on all 4

but i shall check them!

fair play man i shall have a perve!

it just i dont have much time what so ever to fuck about with it, so wanna try and narrow it down to as little as possible if that makes sense?

cheers for the help lads!

Think back to each time this happens, are the weather conditions wet everytime it happens ?(if problem is still occurring).

24th March 2013, 23:25

it hasnt done it in the past 3 or 4 days mate, and it did it what ever the weather conditions were like or whether the engine was warm or cold, it just did it when it pleased

Slap some Forte injector cleaner in it mate. See if that helps keep it at bay. Avoid redex and all that shit.

we've got some of that forte shit at work

may dump some in !

Some 16vs can run like that, my 106 GTI was a good runner made 130bhp with just a pugsport but it never ran right, always lumpy on cold, changed a lot of sensors even tried to cut out and was terrible on the juice it never bothered me that much as I never did a lot of miles back then.

Mine ran fine in the summer but hated winter hopefully yours is the same

24th March 2013, 23:29

Mate of mine has recently had the same problem..

Would run fine, then go onto 3 cylinders. Put injector cleaner through it and it was fine for a couple of days.
Changed all sorts, turned out to be a duff injector.

fair doos man, might aswell just put some injector cleaner through it, if it does it again afterwards might aswell just whack a new injector in, also need a new alternator tensioner

mines now started making a horrible horrible noise! fucking 55 quid + vat are those cunts from pages etc :O

24th March 2013, 23:43

Also redex got mentioned, i put that into my vtr and fucked my injector seals, evil evil stuff

Well it sounds identical to a problem I've had, I kept trying all these ideas I had but nothing worked until I have up and took it to my auto electrician.

He told me that it only happened in the wet (I thought it was just being random) and that water was leaking through the screen wash jets and leaking onto the injector loom 3 (on French it's second one in from timing belt) and it had eaten away at the loom.

It's an easy fix but I'm about 120% sure from reading everything that's what you have.
