Hope you guys can help but my car is starting to play up big time WHEN cold , she is missing and is lumpy for about 5 mins until she warms up , but she has also stated being a bit lumpy when i put my foot down !! Could this be a pump issue

thanks in advance

 

black smoke when warm ?

Could be your CTS ( the blue one in back of head ), assuming its a cossie

 

i can only say i have seen puffs of smoke after a good blast when pulling of from lights ( say after a motorway session ) and yes she is a saff 4x4 coz ...

 

problem solved guys ,,, one of the leads was earthing out ,,,, , for a change a nice easy fix !!!

 

hi mate

glad you solved problem, funny enough that was also the problem with mine
