Hi guys started my fiesta up for the first time in a year since i have converted to the t3 and fitted beige injectors/ front mount, and i seem to have a slight missfire at low revs but it clears if you rev it abit more, the cars due to go off and be set up soon so im assuming the new injectors might be the reason?, i do have 1 odd lead but it has always been there and never been a problem.....any ideas? cheers

 

I would start with new plugs and leads mate

 

Thanks for your reply bud i have ordered some new plugs and leads, the plugs havent had much use but i took the odd one out to check it and it was soot black. which i assume is overfuelling?

 

Presumably you are using the same chip but with bigger injectors until you get it set up. I am assuming beige injectors whatever they are, are bigger than the standard ones? If so, then a rich miss-fire a low revs will be the cause as indicated by soot black plugs.

 

cheers mate i have a superchip but not sure if is a 165 or 195, as they both look the same :S
