Corsa-B.uk - Vauxhall, Opel and Holden Corsa B Owners Club

iv got a corsa b merit but its got a 1600 sport engine in it and its running crap. there is no power n when i put my foot down its bogging n wont go anywhere ive had it pluged in and it came up with the map sensor voltage too high, fuel pump relay voltage low and egr position. ive changed the map sensor the cam sensor and the fuel pump relay and its still exactly the same. i was going to change the egr but was told it wouldnt cause it to lose power and bog. need some help wiv this guys its realy starting to get on ma nerves and dont no what else to do wih it.
