Any decent independent garage should be able to read the ECU fault codes and advise what work needs doing  :y
unless by "garage" you mean petrol station  :-\

If they triad to up the revs mechanically, then of course the ecu stopped them, that's it's job. I suggest you find a garage with actual mechanics in it.

sounds like they don't have a clue what they are doing
did they say what the fault code was ?
what are the symptoms ? apart from the money light (engine management light) being on ?

Car struggling on start up once up and running going fine
probably something simple like the ecu coolant temperature sensor
I'd consider taking it to another garage to get a proper diagnosis with live data and reading the stored fault codes  :y
correct diagnosis is very important ,swapping big expensive parts (like ECUs) in the HOPE of curing a fault is not the way to go  :(

2.2 petrol
Cam sensor, especially if the car is showing a gearbox code.

Only replace with a genuine one from a genuine Vauxhall dealer that you genuinely have to walk into.  :y

Seconded. Failing cam sensor is the most common cause of running problems on 2.2 and must be replaced by genuine GM item.

I would suggest cam sensor, though it normally throws a P0340.

I would get some better diags first, plus somebody needs to undo the (incorrect and stupid) changes the last garage did.

Desmond might throw a gearbox code, but rarely a cam sensor one  ;)
