Irregular idle and lack of power....


Recommended Posts

This has just started to happen...

Starting the car takes a min then when you set off it pulls back ( i had a kangaroo effect today with foot flat on floor). When it clears the acceleration is awesome but then pulls back after 2-3 seconds and just seems really under-powered. The handbrake light flashes when booting it.

when stationary: Idle falls then goes back up to 'normal' several times in a minute

Most serious case so far linked with this is when i have slowed for a roundabout, braking and clutch depressed, go for 2nd and the car has stalled....No power steering or anything!

I had put Redex in the tank to clean the injectors etc to try and cure the stalling and iregular idle

I think it might be the fuel filter blocked and need replacing but would like some other views...

It is a '92 OBD1.

It a cylidrical bit of plastic with 1 centre plug and 6 around it on the side of the block. is a coilpack the rectangular type?

I thought about cleaning the MAF and throttle body and will now be done, could get dirty as it has a pipercross fiter attatched.. that will be cleaned too.

I have some replacement HT leads so would it be wise to replace the plugs aswell?

I am a dub head :-p but this is my first VR... totally different breed! lol (6)

The car has done just under 93k

yeah thats a distributor mate and yeah the coilpack is the rectangular one :)

yeah electrical contact cleaner is the best thing to use to clean them - yeah can replace the leads and plugs as well always worth it if you still have the original ones on mate

Top man.... do you think i should replace the fuel filter aswell? after reading on here about a VR Ibiza with similar probs that was suggested as the culprit....

The only downside about getting another car that isnt Brand New, is the fault finding of silly annoying problems!! lol :^) :S

Ok no worries. Ive seen them advertised around £40 on the back cover of PVW. maybe a worthwhile investment. Would it work for a 1997 GTI 16V aswell?

I wanna make sure both motors are running sweet for the Volksfest/ Run to the Sun Bash... Its some few hundred miles!!

for the fuel filter I would phone GSF and see what price they have mate especially with your premium member discount I would think they would be cheapest

Will do... i totally forgot about membership discounts!

£40 is for a vag-com diagnostics reader... from Gendan.co.uk/pvw

Most ive found tho are for 1996 models onwards...

Also found something at BSRUK.co.uk

if you've got access to a mk3 16v you could also try swapping the coil to the vr - the plugs will fit - in case the 17yr old one is on it's way out.

Have a look in members rides an projects....... VR6 and 16v...... more than just them pictured lol.

I never thought of that... i knew the 2 top end mk3 shared alot but would tht really work??... 4cyl coilpack and 6cyl dizzy, im not sure.. and if it did ... the missus would have a fit! :S would it work???

well the obvious things to check are the MAF - easy to take off and clean and the throttle body again easy to remove and clean - it sounds a lot like my prob but that was caused by the coilpack which was cracked but as yours is obd1 92 I presume you have a distributor ?

Is this the right stuff?? the CRC stuff can only be bought from the states it seems..... http://www.maplin.co.uk/CONTACT_CLEANER.search

Snap! Big up the dizzy posse.

I remember now. the stealth corrado.

my VR coil went at the end of last year and as I had a spare 16v one left from trying to cure a misfire on that, I tried it and it fixed the non start problem and was fine for the few months it took to source a VR one at a decent price.

obviously the smaller coil would have a shortler life in the long run but to check to see if it cures the VR's symptoms it'll be cool.

worth the effort as with those symptoms in a newer one people would suggest coilpack - as they do for everything ;-)

Right... Ive cleaned the MAF and throttle body with the cleaner from Halfords... Still not accelerating as fast as it shud! :-( I had a Volvo s40 and mazda 6 2.2 pulling away from me until it picked up for a brief moment.. i shud have blitz them. i think the gti would keep up at the mo. And it stalled twice slowing down into second again. AAAARRRGGHH!

Im wondering if the induction filter maybe doing more bad instead of good by drawing in hot air, engine bay was rather warm when opened the bonnet after but would it have that much affect?

iv been looking at vagcom but abit stuck... found downloads but not sure which one i would need. 3 types on RossTech.com

you'll need an adapter from the big 16(?) pin one to two x two pin plugs. some ebay leads come with free ones. and then it'll work a treat. better than OBD2 on my 16 valver in fact.

the port will be behind the blanking plates next to the rear demist switch.
