Injection Systems

[neiloakley]

One of my injectors is stuck open on my two litre. It is a 20SEH engine. Whats the best thing to do? I can either get a new one (60+vat from vauxhall), or get one from a scrappy. Unless anyone knows a cheap place. Also, what injection system would i have?

Is it Motronic M2.5 or Motronic ML4.1?
I looked on the ECU but all it says is Bosch Motronic
