Hi Guys, my daughter has a 2006 focus zetec with 80,000 on the clock that she only just purchased. The thing has a full ford service history and starts first time everytime when its cold but after it warms up it takes some cranking to get it started? any ideas would be appreciated because i am a carby and points type of guy all these sensors and stuff give me a headache

Further info, i realised that during the few times i have driven it i was having issues with keeping a constant low rpm most difficult from a standing start. So it idles fine, nice and smooth but when you accelerate the tinyest bit it revs up in a hurry so lots of slipping the clutch to make a smooth takeoff. Now i believe the 2 things are related i think the accelerator has issues and these are a drive by wire thing arent they? So if the pot or whatever it is that generates the signal has worn, it could be the answer?
Thoughts? |

could also need the intake throttle cleaned as it can get full of greasy stuff from the Exhaust recycle system. Fairlty easy to remove and you buy c spray can of carby cleaner and go for it.

Ok i can understand the carby cleaner on the moving parts of the intake, but is that something that they dont do at a dealer service? Secondly is that the sort of thing to expect after 80,000km?

its an extra at dealer service and yes its probably warranted at 80,000klm The more klms the more frequently you may need to do it if that is the problem This is way cheaper than a problem with the accelerator/throttle sensors so worth a try first.

I agree with marg99, I'd be removing the throttle body and giving it a good clean. And also making sure the air filter isn't clogged up either.

All the petrol 2 litre Focuses LS model do that. Treat it like a diesel when you are restarting when its hot. Turn the key to start and wait 20 seconds before firing it up usually works, we just sold our Ls and it always did it even though we had it log book serviced up until the 13500 when it wa sold.
This hot starting thing is a quirk, scroll through the Focus posts and you will find other comments. |

SJG, the throttle body has 4 retaining bolts. It has a reusable gasket. After cleaning, re-torque the bolts to 10Nm / 7lbft.
Definitely worth checking the air filter while you're there. I've never had any hot start trouble. Only cold start, which ended up being my battery dying a slow death. |

P.S do i need to disconnect any wires, any tricky connectors or such? I did notice the clamp holding the flexible air intake pipe to the throttlebody was so loose it was doing nothing i could slide that pipe straight off, easy as, so if it's meant to be sealed it wasn't ![]() Cheers for all the help guys, i am learning as fast as i can ![]() Steve. |

Even though my throttle body is non-standard, it is still a Ford product, nearly identical to the original throttle body, just with a bigger bore.
Since the Focus throttle body is drive-by-wire (as opposed to cable actuated), there is a wire connector to disconnect from the throttle body when you remove it. And the loose hose clamp situation is no good - I'd replace it with a new hose clamp. |

Larger throttle body = more air flow capability, did you re program your fuel curve or use different injectors and did you change camshafts to take advatage of the ability to flow more air or are these variable cam timing things that can be tweaked? Not that my daughter would like me making these mods to her car

Unfortunately no variable cam timing on these engines. Had a look at cams at one stage, but install costs were going to be huge, relative to the gains that could be had.
I just run a generic SCT tune from Bullet Performance Racing to take advantage of the intake / exhaust mods. |

$800...wow.
Still, the Haynes manual has everything you need, except for a bottom end rebuild guide. |

ok you clever guys, ill throw this in. The O2 sensor? they wear out, go out of calibration, but are required operating data, do they show an error code, or is it only if it fails, its only that this waiting with the power on seems like an O2 sensor heating up or playing up maybe? If this one does it still i will swap the sensor with a good one and see

The oxy sensor usually throws a code and the idle is rougher and car uses more fuel than usual. Expect them to fail only after about 80,000klm or more
