Skoda Octavia 1.8 Turbo 20 valve (petrol) year 2000

[TheMotorist]

I have a year 2000 Octavia 1.8 20 valve turbo automatic. It drives perfectly in normal conditions but if I accelerate hard, moments later the engine dies. I lose all acceleration the car gradually slows and when I stop, it either ticks over erratically or stalls. If I switch off the engine and re-start it moments later it runs fine.

Any ideas what the cure is please?

does the engine management light come on at all?

Thanks for your interest. Yes, the engine management light is on permanently.
I've taken the car to 2 garages . One has fitted 2 new lambda sensors and the other traced the fault to and replaced a weak pressure hose. However, on each occasion the engine management light has gone off for only a few days then returned. So far costing me almost £400 with no improvement.

if the management light is on then its flagging the fault so you really need to get a fault code reader on it and see what it says,i would buy one from ebay for around £30 and do it yourself. its very easy to use and at least you can see the fault codes for yourself which are readily available on the internet

Give Jabba Sport a call, they may be able to help. Usually pretty helpful guys, although the journey is a bit far to Peterborough for you. They may be able to recommend a specialist down your way too.

I've got the same engine in my golf, although it's a manual. I had a similar problem (although the car wasn't stalling) which turned out to be two faulty ignition coils. I understand ignition coils can be tempramental on this engine.

The garage used a code reader to diagnose it though and diagnosed two other faults caused due to the rough running.

It might be worth trying the Club Gti forum here. Although it primarily specialises in VW's there is a forum for Audi/Seat/Skoda as the 1.8 turbo engine is used in all the makes.

Good luck!
