i fitted a milltek 4-2-1 on my zetec s at christmas and when lengthing the lambda i crimped the wires hoping this would b good enough. now it never run right, wouldnt idle and if i put any throttle down revs would drop to around 300rpm and it would jus about stay runnin. i unplugged it and bein lazy its been like that since!

should i have soldered the wires? i didnt put any sealer on it either which was stupid lol but i was in a rush to get 2 brighton for a christmas party.

the lambda is a fuel parts copy but i think they make them for ford so that shouldnt b a issue! might extend the old 1 and try it on it as i replaced it without reason ages ago lol

cheers ken
