Lack of power intermittently, foot full down but nothing happens

[hanners]

Hi,

Wondered if anyone had a similar issues to this one;
I put my foot on the accelerator to speed up and nothing happens. It’s beyond lag. It seems to be in all gears. It also seems to be intermittent. I had a similar issue before but it was more subtle and that turned out to be injector 3, cylinder 3, and the electrical loom. Starting was also issue with miss firing and the error light coming up, with the injector issues. I got the injector and it’s loom changed about 6 months ago and haven’t had issues since. This lack of oomph/response/power is much more pronounced in this case. Belts and water pump were done also about 6 months ago too.

Driving an 03 1.9 tdi

Any thoughts advice on this very welcome.

Cheers
Mark
