what ??

[OP]

Just sorted mine, turned out to be one of the HT leads was arcing inside the spark plug cover. Also had the computers reset to factory settings and it's now flying
Bosch injection specialist near me said that a lot of people tamper with settings over the years without the right equipment. A lot of problems can be sorted with a simple re set.

Hi,

I have a problem with my mk3 Gti 2.0 8 valve Golf that sounds similar: When I'm on the motorway (and pretty much anywhere else when I can get over 50 mph) and I'm on part throttle (not quite on the over-run, not accelerating, just cruising really) the car seems to stutter. All of a sudden for a split second it's as if the engine cuts out and you get a jolt through the car and then it's fine again. It doesn't seem to do it when accelerating or braking and it doesn't do it when cold. The gauges don't die and the stutter is really quick, over in a flash. It doesn't feel like a fuel problem i.e. no loss in power (apart from during the split second), no missing or popping - but obviously I can't be sure.

I've replaced the plugs and coil and fairly recently the water temp sensor, before I spend more cash on the leads, cap and rotor arms does anybody have and ideas as to what could be causing the problem?

All suggestions gratefully received!!

MAx you have the exact same prob as my MK3, try disconnecting the 3 pin plug on the maf and then go for a spin, my car is transformed although the fuel consumption goes out the window and it doesnt idle well. So a new MAF should sort me out a treat.

I might try this maf thing see if mine goes any better

Been there had that on my VR6, get your leads replaced and get you car's brains reset by a good VW garage as you can bet your codes are all mixed up just like wot mine were. (man that sounded soooo common!)
From that they will be able to tell you all thas wrong and you can get wot needs doing instead of everything else that dont!  Could save you a packet!

I disconnected my MAF.

Woaw - the car feels like a GTi again.

Thanks peeps
