Hello, Before lock down my polo 6n1 1.4 cl would not start. I tried it a few days later and it started but when going 70 mph for a few minutes all of a sudden I would loose acceleration for about 10/15 seconds then it would kick back in again, I have checked that there was a spark from the spark plugs (plugs, leads, rotor arm, dizzy cap fairly new), checked for any faults and the only fault was the lambda sensor so I replaced that but still N/G. I then changed the fuel filter and fuel pump and got the injectors cleaned but it still the same. I have just tried changing the MAF sensor and throttle body and was working alright for a few days but on the third day it happened again. It as also happened not just at high speed but now happens at 50 mph and also slows down to about 30 mph before it kicks back in. I am running out of ideas and any advice/ help would be appreciated.

 

Thanks

Welcome to the forum.

 

It could well be that the Hall sensor in the distributor is starting to play up - these things aren't 'self healing', what generally happens is that the engine just cuts out and won't re-start, leaving it to stand for a while (half an hour) generally allows it to start again, but at that stage, the Hall sensor is in its death throws and needs to be replaced.

The easiest and possibly best way to deal with this, is to fit a new distributor.

It is possible to fit a new sensor to the distributor, but unless you are adapt at working with small components, I wouldn't recommend that you try to do so.

 

Before going down that road, it might pay to double check that the connections to the ignition coil and distributor are clean and in good condition.
