Technical Punto 1.2 16V Loss of Power under any load

[GosportNewbie]

My car so far has the following problem,it seems to idle ok, starts up, you may even from time to time be able to rev it.

However try driving and putting any pressure on the throttle and it drops power and cuts out unless you take you foot right off.

It will basically only move when it no pressure is put on the throttle.

I have so far replaced, Plugs, HT Leads, Coils, ECU, MAP sensor.

Anything else to try?

i would compression test it next.

I was wondering if it was the Lamda sensor?

well that wouldn't affect it when its cold so if it does it when you first start it, unlikely. The timing belt could have slipped a tooth or two.. So check timing and do a compression test.
