hi i have focus rs and just started to get a missfire and cuttin out when i try and boot it i have changed the plugs leads and thinkin of changin the lamber sensors. help !!!!!!
when you changed plugs and leads did you do the coil.
As the coil fails which is a common fault on focus mk1 mk2 which in turn tends to take 2 plug leads out. i hav had the same problem with my focus.
