Hi all,

I have a vauxhall astra J 2010. Its currently got a power issue. Basically, when the engine is warm (generally only notice then) the car seems to lack power when accelerating. Its like accelerating hard in fifth, but really your in third. I expect a lot more power which it normally gives me. Its temperamental so doesnt do this all the time.

Its the 1.6 litre petrol engine, engine code A16XER I think.

I have taken it into a VX dealership and conected it to their diagnostics but it doesnt show anything and the engine management light doesnt show at any point. Any tips would be greatly appreciated.

Thanks
