For the past couple of months the engine randomly cuts out when stationary or starts →revs up and either cuts out instantly or slowly with the whole car shaking.Also whilst driving it feels like it's suffocating i.e not the normal amount of power readily available (if that makes sense). This issue is very random. I could drive the whole day without any problems but on another day constantly cuts out, but it fires up instantly. I have replaced the breather pipes, air filter and had a stab at cleaning the throttle plate in situ.the Now thinking of removing it and doing a proper clean. The fuel filter isn't too old and my mileage is very low 5000m a year, but will clean that also. Anything else I could try before giving up and taking it to my "friendly" indie? Thanks.
