i have this rs turbo that keeps playing aronud so i brought a new dizzy for it tryed it and the car wont start so i then brought another one off of a running car and still the same thing but as soon as i put the old one back on the car fires staright away the thing is if i have it set to std timing marks the car does not like to idle and is as flat as any think but if you twist the dizzy right round it idles and goes like a rocket but knocks i have changed the ecu as well but this didnt help, the only thing i can see is that some one has fitted a 90 spec loom one with knock sensor to the car but it has a 88 spec ecu engine metering unit etc etc,
