I thought it must be the fuel pump/filter so changed them both - problem still remains - car starts fine - but will only rev up to a point and then not go any higher - on driving it lacks power and won't go faster than about 20 mph.
Help

Sounds like the transmission isn't changing gears. Can you rev it high when its in neutral? Have you tried putting it into different gears?

Sounds like the car is in limp mode, get the car scanned for any codes that would cause it go into limp mode.

I have scanned the car and I get 00513 - engine speed sensor - Where is this located?
