Ford Focus Mk1 Common Problems Thread

In need of some advice be grateful if anyone can help.

I have a 1999 Focus 1.8 Petrol.

Over the last few weeks I've noticed the speedo drops to zero but picks back up after a minute or so.

But today it never picked back up and when I slowed down and the revs dropped and the engine cut out it started back up fine but continued to do it several times.

I done the key test and found it had 2 dtc codes

dtc123-throttle position sensor/switch A circuit high input

dtc041- cant find the description

Has anyone else had this issue or managed to resolve it 

Also if anyone can fix it or knows of a good garage in the Croydon area it would be helpful

 

As Peter has said regarding the speedo, that will likely be the sensor on the gearbox, needs replacing.

Hi guys, after read this topic I have a question...

I recentrly replaced the VSS sensor of my Focus Zetec 1.6 and now still bouncing the speed, but the car goes much better now. But the main problem is that when idle, randomly (not always but very often) the revs fluctuates between 500 and 1000-1100 (aprox). It's very annoying... IAC valve replaced, PCV hose replaced (was broken), and ome other hoses of vaccum replaced too... WHAT'S THAT !!??

2 years trying to solve this with no results... 😢

Thanks, Alex.

Hi

I've had a 2000 mk1 1.8 petrol estate for the last 4 years. After 207000 miles the MOT became uneconomical to carry on ,even though it still runs good, the body is shot.

So I went out on Wednesday and bought a similar car with 75000 miles.

It went great for the first 100 miles then on Friday morning it felt like it dropped a cylinder at a red light.

I carried on another mile to work and found the mid section of the exhaust had split. Fitted a new one and started looking for the misfire. By now it was on 2 cylinders.

I still have the old car with the high miles so I started swapping components.

First the plug leads, no change.

Rear PCV hose was split and taped up, fitted a new one, ran better but lost idle.

Then the Airbox, no change.

Coil Pack, no change

Idle control valve, got idle back.

PCV, ran on 4 at higher rpm.

Cleaned Throttle body and swapped Throttle Position sensor, idle went steady but still low at about 800 rpm. Revved out clean but went back into 3 cylinders after 2 miles. still revs out and comes onto 4 at higher rpm when I stomp on it. 

Any one else seen this? Any ideas

All parts fitted today came off a car I did 1000 miles in last week. So they all worked.

Update:- Yesterday I fitted a couple of obvious service parts, Fuel filter and new plugs. It still wasn't right but it was just about driveable. Took it up the motorway and was running slugish. In particular it didn't like hills. I'd had a similar experience with the previous car which was a Catalytic converter falling apart. They are cheap so I fitting a new one. 

The misfire is still there and I've now noticed the Cat Glows red hot after a short drive. I've inspected the old Cat, and other than being a bit blocked, its not burnt up like you'd expect.

Tonight I pulled it all apart and confirmed Cam timing has not slipped or jumped a tooth. I've done belts on these before, so have the tool kit and I know them well enough that its a fast check for me.

While I was doing that I found Plugs 1 & 4 were sooty, cleaned them and it run up on 4. Took it for a quick drive, and it was back to running rough and Cat pipe glowing again. Switched it off and opened a Can of Guinness.

Any input gratefully received and hopefully it may help someone else in the future as these fault are never one-off.

I'll post more as I go. I know this has the potential to be a great car again.

Good point rust missed that one no experience of the diesel so cant comment on them rear arches rust badly as do the bottoms of the doors check electrics and aircon if fitted works listen for engine noises loud tapping etc check when the cambelt was done ignore the 10 year 100k rubbish youll be told many rarely get that far

Our Mk1 auto estate 1.6 Zetec is 18yrs old (134,000m) and  I do not agree with this, apart from rusting at the seams.  The Yamaha designed engine has a very sturdy cambelt design driving only a tensioner pulley and two small camshafts which spread what little load there is.  It was designed to last at least 150,000m and they very rarely fail.  I am certainly not risking a cack-handed apprentice exchanging a belt which still looks like new for possibly an inferior product and putting one or both cam cogs a tooth or two out of synch. The 10yr 100,000m advice is merely precautionary.  If you must change something, change the tension pulley as this is far more likely to fail than the aramid belt which is so strong that only slightly thicker ones are used to drive powerful motor bikes.

how are things going? I have a misfire or two on my car with 160k. so far replaced the plugs, leads, coilpack, ISCV, MAF, fuel pump (a new Bosch one), fuel filter, lambda sensor, compression check (all between 175-190psi). and still I have a misfire under heavy load/mashing my right-foot down. which is usually worse or much worse when my car is below half a tank. I have a bit of vacuum with my hand over the oil cap hole so i think PCV is okay and its so rusty i don't want to touch it for now. I snapped one of the screws holding the throttle body off when i tried to unsrew it lol. its made no difference though o nothing to worry about maybe.

I've a few other electrical age related gremlins but nothing as far as I can tell in the engine management has come up for a long time on my forscan setup. 

I've reset the module since putting the new bits in and after a few days driving its back to what it was before. I trained in a ford garage when the focus was released but we didn't come across stuff like this as all we tended to do to them was 10k services and recalls then I left the garage in 02 and haven't really had anything to do with them until now. 

If it had failed mot this year it'd probably have gone already but it passed even with the misfire. So what's the score with you?

your filler neck pipe is rotten? it's metal (steel - pretty dumb i know) all the way from behind the nozzle part down to the 2" rubber pipe that joins it to the tank. Mine leaks like a seive if i brim it and the rust accumulates inside the fuel pump and blocks the strainer every 1000 miles or so. 

I forgot about this :laugh:

I have a knocking coming from the left front of my car. It only happens at around 20 to 30 mph. My car passed it's MOT in November, and no mention of worn bushes etc. I only get this around our estate at low speeds, the car is fine on main roads, dual carriage way etc. Anyone know what it could be?

Hi all.

I have a 5dr 1.6 zetec 53 plate, with a couple of issues.....

1) clutch pedal bite is very high & thrust bearing squeaks a bit 

2) while accelerating, in most gears it coughs once or twice but then seems ok 

3) drivers door handle (inside) has recently broken.... the exterior door handle works but only just, as the handle is almost at full extension before it delatches.

 

Any suggestions of help anyone??

Thanks in advance

Daz Barker
