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!!
