Hi all back again my Ford Focus 2002 has still got a slight misfire (1800 revs) despite changing coil, leads and air filter. This has been going on for 2years now, now recently the engine warning light has just started coming on and going off, some time the engine will not start just dead I have to hold the key on and after 10 or so seconds it starts up, also when it's very cold all the dials on the dash start flickering. Any ideas, is it worth spending the money on it at a garage its in great condition we've owned it from new and always passes the mot. Thanks for any replies.
