It drove fine but when I got off the motor way and into town it started smoking loads of smoke and the accelerator made a weird noise

Hello Mrs Featherbottom, Thank you for taking time to go over my Q&A history. Yes, some of my recent answers have been repetitive. I learned to do this for many reasons, such as allowing me to not only reach more people needing help but to also get the information required to get the problem solved. In your instance, if you did have malfunction indicator lights illuminate on your dash they could be scanned for codes and the codes would tell us precisely what needs to be rebuilt/replaced. If there are no codes, for example, this would typically imply the the problem could be mechanical. I am only here to help.
