I have a 2wd sapphire cos and first thing in the morning it starts fine, after a second or two it starts to missfire and appears to over fuel, while like this if you try to drive it, it will stall and be a sod to re start, if you leave it to tick over for 10mins it will be ok, but it still feels slightly flat. she is running yellow injectors unknown chip, low compression pistons stg 2 hybrid turbo. all the sensors appear to check out ok and the amal valve is working. The only thing I haven't changed is the ecu, although I have tried a chip. has anyone got any ideas.
Also does anyone know where you can get a new engine loom, and roughly how much, as my car is the one that caught fire at castle coombe on the 10th of july, and although running just the same as before, it could do with a new loom.
