Hi All!

I have I have a Focus Zetec 1.8 petrol (duratec engine) 56 plate it’s done about 66k miles.

I’ve only just started to drive this as I’ve only just passed my test :) but something just doesn’t seem right with it … It seems sluggish when pulling off and easy to stall and at times it won’t start unless I press the accelerator. I’ve done some research and I’m going to have a go at cleaning the throttle body to see if that helps. I was also going to clean the MAF sensor but I’ve just read that the 1.8 doesn’t have one? I’m also going to look at replacing the coil pack but I’m unsure of which one is the right one to buy as there are lots of different designs out there. It’s just had a major service but that didn’t seem to help either.

Any help would be appreciated guys.

Idle control valve or a collapsed vacume hose at the rear of the throttle body

Thanks for your reply Arthur. Is the idle control valve easy to get to? also is it something I could clean up maybe? I'll have a look at the hoses too. if it is a bad hose would it be easily noticeable on inspection?

Sorry just noticed its a 56 plate so I'm not sure if it has an idle control valve IDE have diagnostics done on it as it could be and its a long list

Coil pack need a genuine ford one which I Bosch

Leads which again cheap ones wont do £60 ish from ford

Collapsed vacume hose if present it will be at the rear of the throttle body collapses on acceleration

Camshaft sensor

Maf sensor

Faulty 02 sensor

Faulty injector or even fuel pump

Without diagnostics and fault codes you coil spend a small fortune replacing the parts

As Artscot says, it is worth investing in a fault code reader which are cheap enough on ebay before wasting money on the wrong parts. We have all tried the guessing game and unfortunately it never usually pays off.

I have a OBD2 reader but no faults are showing. so I think taking it for a diagnostic at the dealer wont return any results.

also last week when I first began to drive this car the engine management light came on after it had stalled/failed to start!

but it went of buy itself and since then I've disconnected the battery so there isn't any stored codes.

The engine management light has not reappeared though

I could try and post a picture of the live feed from the OBD2 reader if that would help?

UPDATE- I have now found a code P2008.



I've just read that this could mean a number of things though?
