well when its ticking over its running very rich whether its got blue or beige injectors in or if the chip is plugged in or not,it will rev up but sounds like it misses a bit but will rev past it,then when i try 2 drive it as soon as it starts 2 come on boost it starts 2 cough and splutter and impossible 2 drive but as soon as u dip the clutch it will rev up until it gets loaded up again when i lift the clutch,the co pot doesnt seem 2 make any difference when its adjusted either way so i thought it might b that but sum1 said its not,it might just need setting up but i didnt want 2 take it 4 a setup and there b a problem that i havnt noticed
