A lot of modern vehicles have so many computer systems that if they detect something wrong, the engines operate in a limited power mode, as mentioned to try and limit any damage to components. I believe quite a few of Redcars Pulsars are in limp mode... Stocktons tend to get sorted pretty quickly, although we have a few regulars (1490...)
