missfire from start up cold

[bbvw]

hi people as above, then when warm it runs ok ish. has new knock and temp and co pot sensors. timing ok. chip done by jabba sport (custom) wires seem ok aswell! any help please!?

I had this on mine and it was just a dodgy HT lead; I would try a new set if you haven't already swapped them. Also check inside of dizzy cap for black lines between the contacts where the sparks are going astray; this can happen if it gets damp or oily.

thanks for replys, will check them out but it has new gsf leadz and cap and rotor arm. have heard that the hall sensor can be faulty but i dont know how to test it? think mine might have a small leak of oil coming through the dizzy shaft do you think that could do it?

its all on ok and the hall sensor connection is at the top but the part that reads it is at the bottom so thought it might be that covered in oil, would that really cause it to do what i said?
