Hi my vw golf is really lacking a lot of power it's the 1.6 fsi mk5 and in good condition it's been serviced every year not got high mileage and has been taken care of. Lately though it is really struggling with power I can't get it much over 70 mph it lacks acceleration but ticks over just fine with no other symptoms I have plugged a computer in and it's reading some faith codes
Air intake temperature sensor, fuel measuring system malfunction and exhaust gas sensor I have no Luke as to what I should do next so your help would be greatly appreciated

Could be carbon build-up on the intake valves... this can be cleaned-off by blasting the valves with walnut shells (while the valves are closed).

I have not had a chance to make my own video, but here is one that I found on youtube:

They can be cleaned manually with a liquid and a tool pick: (google search result)

There could be other reasons for your power loss... some investigating will be required.
