Hi!

 

I have a very unique problem, and as I tried to figure it out, a couple of owners told me, that they have the same problem, and even the official service can not solve that for them.

So, when I accelerate and reach the 1700-1800 revs, then for half a second the acceleration stops, it is like whether the spark plug stops working, whether there is no fuel. It is weird, but the most weird is that the car does not do this every time. There can be a whole day, and I do not feel this, then the other day I feel. I felt it for a couple of times at 3500 revs. The gearbox position does not influence this, when I fell it can be in 1, 2, 3 gear.

The car is 2005 year built, hatchback, 1,4 liter, 100 Hp, motorcode BBZ.

I buy petrol at official stations, mostly one station, and it is 95 octane. The spark plug and the petrol filter were changed not long ago, so they should be OK.

Does anybody has any usefull information for this problem?

Thanks a lot!

I would have said spark plugs or fuel filter but you've already replaced them so next thing would be the coil pack. 

What’s a non official petrol station

E.g. I buy petrol in cans from people I do not know.

 

Check that the battery connections are tight.

That's how it started when my BBZ fuel pump needed to be replaced. Expect the car to "die" for no reason, only to start again as if nothing happened. Anyway check all your fuses and electrical connections, battery and grounds, but if I were you, having passed through the same symptoms, I'd start looking for a new genuine fuel pump, or I would clean and check its electrical connections for tightness at the very least. 

 

In my case, it started to die on hills with the A/C on. You would downshift to pass a lorry and then... nothing, felt as if you turned the ignition off while driving. Turning it off and on again solved the issue generally... Until it no longer did and I had to get whatever pump would fit since I was stranded. Ended up putting an Audi A3 pump which fit and was in stock right where I was, not to mention it was half the price of the Škoda part which took 3 to 5 business days to arrive. That solved my problem, even if the Audi part is a 90 lph unit and the Škoda is a 100 lph I believe. It was as simple as getting the old fuel delivery unit and dropping the new one in place. Only thing I had to carry out from the old one was the sender for the fuel gauge.

 

Not saying it's necessarily your problem, but that's what happened to me. 

 

Would be nice to have a sort of logger plugged in while you drive to narrow down what happens when your car does what it does.
