Hi there - thought I'd post it here since this BBS is a fountain of all knowledge !

Got a 1996 Golf GTi 8V as a runner for work. 67kmiles and FVAGSH.
Recently had all plugs , rotor/cap replaced since it was stalling.

It starts and runs fine 99% of the time.
However - when its warmed up and doing say a constant 70 or 80mph on the motorway it will suddenly stutter with a temporary loss of power (revs drop etc). After about 1 sec its back to normal. It doesn't seem to do it under load as such - just at constant cruising speeds.....

Anyone any clues ?
Does the car have a MAF ?? Could that be it ?

I can't see it ever having had new spark plugs - so I thought would be a good start......

HELP ! before the thing lets me down

a friend with the same model had this problem, I'll ask him how it was fixed. Got a feeling his was a dodgy lamda sensor.

Gastro

Cheers .......... look forward to hearing about that.

Monkeybone

yeah he said his was the lambda sensor, although he also had dodgy idling as well.

I have just had a similar problem with my wife's MK3 although ours would start cutting out when fully warmed up, turned out to be the crankshaft sensor, although I ended up replacing the temp and lambda sensors as well, hope it helps

worth checking any vacuum pipes for perishing at the joints

Gastro

Cheers for the info.

Its going in for some diagnostics. I'm 99% sure its a sensor issue.
I get the feelihg it will cut out eventually if I don't do something sharpish !

There were a few threads on this a while ago (my mum's car had same problem). On quite a few cars, where it's not the relay for the fuel pump, lambda or the cam sensor it turns out to be a dry joint. You need a good garage or auto electrician as it wont show up on a diagnostics. Think it cost about £50 labor as the guy we used had to check about 50 wires before he found the right one - then £20 to re-solder it. Now it's fine. Seems to eb a common problem of the mark III with that age and mileage.

Gastro

Right...........

The car has had 2 x relays (fuel pump, ignition), throttle body clean, new sparks/HT leads/Distributor

It still does it - and has also started to stall once warm (intermittent) - especially after a good motorway run.

Diagnostics has come up with nothing......

Is it worth getting all the sensors changed ?????? Or should it go in the local paper !

Where is the 'dry joint' problem ??

Thanks in advance.

Gastro

anyone any views ???

Monkeybone

tried the lamda yet?

Gastro

They (the VW dealer) told me that if it was the lamda - it would have shown on the diagnostics !

A dry joint is where the solder in any wiring/on a circuit board has cracked, and hence the elctrical connection isn;t very good/fails. YOuneed a good garage/auto electrician to check each and every wire until he finds the fault - it took our garage 2 hours - i.e £90 labour.

p.s. a dry joint wont show up on a diagnostics test - but his seems to be a very common problem with the Mark III car around this age. Hope you get it sorted.

Matteeboy who posts on here is apparently an expert on Mk3 Golfs - try asking him

did you check the crankshaft sensor?

Gastro

Thanks for the advice guys...... its in the paper next week.
Shame really
