The car was running ok apart from hesitating slightly so put new plugs in, bit better. Had it serviced, not much better and thought it might be the amm. Got a new one from courtenay and put it on and its a lot worse than usual. Will not pull past 80mph in 4th and struggles higher up in 3rd. 2nd seems ok and 5th has a little bit of bother.
Any ideas? Could it be a faulty amm from courtenay? or could it be something more serious? As far as I am aware, it is not chipped and the only thing non-standard is the k&n panel filter.
Any help is muchly appreciated.
