07 reg 1.3.cdti combo van it all starts ok but no control over the throttle what so ever unless I start it with foot to the floor then it will rev to about 5tho rpm but then if I let it idle then go to throttle it again back to no control over the throttle again any ideas would be really helpful I've had a code reader on it and it says air flow sensor and air temperature intake sensor so replaced them with new ones stil got the same codes and having the same problem I've been told it could be the ecu to it could be the egr valve

Hi there well all you have in the circuit is the throttle body, the ecu and the pedal sensors, i would do a code test on it first, it's probably the pedal sensor.....but you ought to check first....might be worth checking the fuses....Fred.

Hi Not really on the fuses, i will put a list of Corsa C below that might be helpful. well egr problems are usually the valve sticking open, you have to take it off and spray some brake cleaner or some solvent on the plunger and make sure it closes....actually having a rethink, its a diesel not a petrol right?, so all that about throttle body is wrong, but i believe you still have sensor on pedal and ecu, but the the air intake doesn't control the fuel, its done at the high pressure pump....if it has swirl flaps on i would make sure there connected and working, their on the inlet manifold i believe....and make sure there are no air leaks from MAF to engine on air trunking.....it might be worth disconnecting the battery for awhile or overnight, that might even cure the problem....also check for any air leaking coming into the high pressure pump, like fuel filter housing for instance...good luck from Fred in Essex.
