Now car will start but won't rev over 2000/2500 rpm, it just dies, When it hits 2000rpm I get a loud 'bang' through exhaust and then engine dies.
I bought new relay module and PCM as thought it might be one of those, only to find out you can't programme them without special software and having trouble in UK to find someone.
I'm now thinking bad Lambda sensor or collapsed Cat' Convertor.
any one please assist.
