Hi Peeps,

Could anyone shed some light on a problem I'm having with my 1.6 Golf Driver MKII

Car is fine on short hops, but if I run it for over say, half an hour at motorway speeds the car will 'judder' at a certain throttle position, then be OK if you push it past it.

Thing is the problem has been getting progressively worse until you can virtually have the pedal to the floor just to keep going.

The problem disappears again once you run it again (or tick along at a slower speed)......?

Help!

Is the engine of the 1.6 driver equipped with a carb or fuel injection? Sounds to me like it's getting fuel starved when working hard, which would explain why it is then OK again at lower loads.

Could be the petrol pump not up to the job at high revs, partially blocked fuel filter, carb float chamber level or injector control.

Alternatively, remembering that HT ignition systems are generally the reliability weakpoint, could feasibly be the coil that is on the way out and once warm and at high demand it is failing to give a strong spark 100% of the time.

I'd check the fuel filter then chuck another coil on and try that. Next port of call would be the fuel pump, but hell, I'm only guessing.....

Best of luck - hopefully someone who know's this engine will be along with further advice - I only really know the 1.8 injection version.

Thanks nel,

It's the 1.6 Carburetted version and here's an update for you....

Drove it down the M1 last night - after about 30 mins, problem occurred again, foot flat to the floor and decelerating.

Pulled onto the hard shoulder coasting in neutral. Then I decided to switch off the ignition and restart. It fired first time and carried on as if nothing had happened....!! So the problem was remedied just by killing the ignition!

I'm sure it will do it again, but it sounds like a fairly simple problem if it can just be solved by switching off then restarting the engine.......?

Thanks for your help

Engine by Microsoft? Fatal error just hit Ctrl Alt Del. Maybe you just need to download the latest upgrade.

Sorry, haven't got any helpful ideas other than it does sound ignition / fuel related rather than mechanical. I'd go with the previous suggestion.
