Disconnect your maf and if nothing changes then it's your maf mate but also do what Chris said reset tour Ecu by disconnecting you battery for like 10 min

Rite guys

Today I tried to get a diagnostic done but couldn't get in today so decided to take matters into my own hands and look further into my problems first I noticed one of my boost control valves connected to my vac pipes wasn't there it had fallen down onto my manifold melting the wires going into the valve so I cut the plug and the bad melted wires off and put on new connection plug this didn't cure the problem so I check the fuses and just by luck there was a 10 amp fuse blown I changed that disconnected the battery for 30 mins and luckily wala the fault is no longer there tho I am loosing boost pressure on the motorway so I shall be checking my vac pipes for pin holes tomorrow.

Thanks for your help guys much appreciated .

Thanks John.
