Thanks thomkas_cars for your response . I have already considered the foot pedal fault but discounted it, since the speed drops when depressing it at speed (E.g. on Motorway).
The car is still under manufacturer's warranty, so how do I get a Vauxhall dealer to do something without them giving me the run around?
I suspect an injection fault. The reason for this is as follows:
About 12 to 13 years ago, just when injection had just become standard, I had a similar fault (but not as bad) on a 1.4 Astra that had done 30K. I took it to a Vauxhall dealer but no fault found. There was no fault codes stored in the ECU. Then several montrhs later whilst they were servicing it they found the problem - an injector. It was fixed and I kept the vehicle was billiant and I eventually replaced it at 90,000 miles.
So my question again is (bearing in mind the vehicle is under manufacturer's warranty), how do I get a Vauxhall dealer to diagnose and fix the fault? (I appreciate that if an injector fault does not show up on the ECU, then it is likely to be time consuming in finding and replacing it).
Again, thanks for your help. Any further suggestions from yourself or other members would be appreciated.
