I'm having lots of ongoing problems with my Focus and am hoping for some advice, its a 2005 mk2 1.6LX (100ps Duratec).
Problems are as follows:
- Starting issues. When starting the car it fires fine but then loses all revs, causing it to stall. This happens 9 times out of ten and does it regardless of whether the engine is hot or cold.
- Misfiring. Seems to have a misfire when held at contant revs between 2-3k and when holding speed/accelerating on the motorway.
The car did originally have a leaking core plug which caused plugs 3 & 4 to be wet. I have replaced this and fitted new Ignition Coil, HT Leads and Spark Plugs. I have also plugged the car into an OBD reader and there are no error codes reported.
Has anyone come across anything similar before? I'm thinking that it is possibly a faulty sensor somewhere but, being electrical, am reluctant to put it into a garage and spend lots on labour for nothing to be found.
Annoyingly I bought the Focus as a supposedly more reliable replacement for an old MG ZS but it has turned out to have far more problems!
Thanks in advance
