I've got a 1.8 140 roadsport SV (02 year on 10k miles) that's a bit of a mare in traffic, at about walking pace it's really hard to drive it smoothly. I've put up with it so far because I try and avoid traffic, but next year I'm going to be commuting in it a lot more.
I wondered if it was driver induced, but no matter how hard I try to be smooth and gentle, if I press the accelerator when crawling it's really jerky. Otherwise it runs brilliantly.
As I understand it I need to get the ECU mapped properly, and this may require fitting vernier pulleys.
Is this correct and will it stop the popping I get occasionally on overrun? (Cos it makes me smile every time)
And the next question is, where's the nearest place to Bristol to get it done and roughly how much should it cost?
