Is this something they would have checked with hoses etc on a service? but if it is that problem do yout take it to a vauxhall garage or get it looked at at a specialist? thanks Cath

Strange for this to happen on a 1.7. Check the turbo? Or do the brake and accelerator test and let us know what code comes up?

To do the pedal test..

Fully press the brake and accelerator pedal.
Turn the key in the ignition 2 clicks, (do not start the engine)

Error codes should be displayed on the tachometer

Fault

Hi
Have been out and done that but no error codes. The problem seems to be after hard acceleration or uphill brings on the loss of power then after several miles or back on the flat and easing back goes back to normal???

Hi Will do. I know it is a small engine, its just the loss of power thing has been happening only in the last couple of months.

It is the 2nd pipe on the right. See if its loose. Also you could check it by grabbing hold of the pipe and getting someone to accelerate!! It should expand as the revs get higher

?

Hi Not sure if its a mk4 its an 04 van! Do they have engine management on them which could be causing the problem as everything works on a day to day basis its only when you accelerate uphill or give it a bit of umphy on motorways???? puzzle...
