2000 Vauxhall Vectra

Engine Performance problem
2000 Vauxhall Vectra 6 cyl Front Wheel Drive Manual 123678 miles

the other day I pranged my vectra. Only damage was broken front grill and one bracket on each headlight. Now every time I drive it, it loses power when I release acceleration pedal then apply power again it carries on as normal. It does this every time I drive it and many times per trip?
not got cruise control. I'll be driving as normal i.E. 30 miles an hour then power goes revs drop to tick over foot in same place on pedel. Remove foot then replace foot car runs fine. This can happen once every 10 mins or 10 times every min.
had a test done it come back with 0120 tps and 0335 crank sensor ecu was reset still doing the same thing. Would these faulte cause this? Cheers

You need to check wiring on the TPS (throttle position sensor) if this seems ok remove and replace the sensor. On the throttle body !
