Puzzled on car now

[Alank]

Well me and my mate had a look at the car yesterday to see if we could find out y its going into limp mode we cleaned the boost sensor and checked all the pipes we could see for splits couldnt find anything he put his computer on and that gave one fault and the Mass Airflow which is new as that was the first thing i changed. Then we went a drive with the computer on to see if everything was reading correctly which he said everything seemed to be fine.

So now where lost of what to do now its funny as it only seems to go into limp mode on one hill down my street when were coming up it i was driving around all day yesterday and it never happened until i got to that hill.

Anyone esle got any advice?

Cheers Alan.

when my galaxy did this it was the actuator that was faulty, the cure for that was to fit a new turbo unit, cured it

Try another mass air flow meter from another car if that dont work try another boost sensor then go from there.
