I have had a scan back through the thread, and noticed one item missing from the lists, and it is the item that probably actually senses the misfire error: The knock sensor.

All the ignition parts have been changed by most here, and fuel injectors by some. But no mention of the knock sensor. Worth checking if all other parts have been changed.

It is 12A699 in the picture here:

Multiple misfire

Phonic wheel relearn

Dash warning lights (Auto start-stop, EOBD injection system failure, Generic failure) later versions also have Tyre pressure low & Hill assist unavailable I believe.

 

Hi all update from my previous posts.

Daughter purchased a 2011 Ford KA June 2019.  (Fiat based) In car history cambelt changer 2016 at a Ford main dealer. Soon after purchase the car would start to have a major misfire if on motorway / duel carriage way when cruising at about 2750 / 3000 rpm, 60 / 65mph. Pull off road switch car off and back on it runs fine until the cruise down the major road but it is random when the next episode will be. I suspect the car was sold with known fault or was a town car as very little miles since cambelt changed.

I changed spark plugs and swapped coil pack and leads off another same year car I own but it still happened. Local garage code read P0300 (multiple misfire) P0302 cylinder 2 misfire detected and P0303 cylinder 3 misfire detected. Pointing to plugs, leads or coil pack, but they have already been changed.

Spending ages on various forums I found quite a number of people reporting the same/similar issues but the threads all went cold without conclusion. Hence my update.

Phonic wheel relearn.

I found a comment about phonic wheel relearn. Reading through and learning about it, crank and cam sensor may be slightly out of timing / synchronisation (not a tooth out just the difference from one belt to another). Various possible ways to correct rev engine to 4000, 5000 or 6000 rpm 3 times letting it idle between revs. Some reports said it has to be plugged into a computer (Ford IDS software) and revved to do the relearn. So without the software I thought nothing to loose picked the middle one 5000 rpm and it seems to have worked.

If you are having issues and don’t want to DIY I would suggest an independent Ford specialist but speak to them about phonic when relearn and ensure that they are aware of it / understand it.

So many people have shelled out loads of cash on parts injectors, coil packs, spark plugs, HT leads ECU’s etc and still not had a result

 

 

Thanks to Gary (ford owners club)

YOU ARE A HERO!! I’ve been chasing this fault since a cambelt change & re-checked the timing a 3 times!! Spoken to ford work shop controller who knew nothing about it & said it would 100% be timing issue. Exact same faults/symptoms as you.

Hi Chris,

 
The pictures and faults you have posted are identical to what I am dealing with. 
 
No I haven't had any luck as yet, been to the local ford garage 3 times with sparks, leads,  injectors and even a battery change. But they are still non the wiser. 
 
Also strange that the cambelt has been mentioned as It was change when I brought the car.  
 
Definitely going to try the DIY method and get the car to 5000 rmp, If not I'll take your advice and find someone who has some experience with phonic wheel relearn.
 
Thanks for the update, your a legend. I'll post my results. 
 
Cheers Charlie

Hi all, I know these are older problems with your cars but I’ve been having issues with the wife’s 2004 StreetKa. Engine warning light came on and it was Idling low, we plugged it in and it came Up cylinder 3 Code! so I changed the coil for a genuine ford coil & plugs / HT leads and a Idle control valve Also a new fuel filter these all did nothing. So the next step is injectors or valves All big money😞 which I didn’t want to spend on a car that’s not worth a lot. So what I did was I put a wynns fuel cleaner in the tank x1 bottle to 20 litres of fuel £6 from the local auto shop and with 5 minutes it was cured. Please try this before going to your local garage it might save you a lot of time and money. Hope this helps

OK, so....

My dad took it to his mate's garage and agreed with my fault finding sequence.

His mate spoke to his mate at a Ford dealer who said it was almost certainly the injector since they did 'two a month' at least. When ringing around for a part, the guy at the local motor factors said that injectors were a common problem on the Ka...in the end, he got a genuine Ford, sorry, Fiat part which was about 150 quid.

For belt and braces, the plug and lead were also changed on cylinder #1 which send a good precaution.

Total cost - £225

Something to note for anyone else with this problem.

Incidentally, the car is just out of warranty and is low mileage....I warned him about buying a Fiat 😉

Hi I have just read your post, I have got the same issue with my ford KA.

I had the cam belt changed on my KA plus I changed the oil, oil filter,spark plugs, leads but it still hasn't fixed the issue with the miss-firing

Many Thanks for pointing me in the phonic wheel direction.

I had the misfire problem with identical symptoms. It was resolved with a phonic wheel relearn.

However I had to use software to do the reset of the PCM (http://www.multiecuscan.net/ licensed version set up as Fiat 500 1.2).

Disconnecting the battery did not do the required reset for me. When the engine requires a re-learn sequence the engine warning light flashes until the sequence is completed.

Hi John, not been looking at this for some time. do i assume you downloaded multiecuscan and now your vehicle is now all sorted?

Yes, all sorted once it did the reset using multiecuscan, followed by the re-learn sequence.
I have not had a repeat of the problem since.

Replace the 'Knock' sensor. That's what is detecting the misfire.

It only happens at 60/70 mph in 5th gear,  turn engine off, restart and away it goes until randomly reaches that speed,  so poss knock sensor?

thanks

Yes quite possibly and a cheaper repair than most of the other stuff you have tried.

You can also try running the car on 'E5' super unleaded (you will need to fill the tank) and see if the misfire goes away, which it could well do.

Hi. I am resurrecting this thread again as I just had same problem with Wife's 2015 1Litre Ka.

Bought the car in January this year it had had plugs and leads when we bought it. It has been fine, but couple of months back it was occasionally hesitant when accelerating.

Yesterday drove from Liverpool to Birmingham and back today, all fine. Filled up with Shell V-Power before returning home.

About 3 hours later we go out, pull away from a junction and it feels like someone has pulled us back ! It picks up then hesitates again at the next junction. I get it home and do a fault read, similar to others I get 0301, 0300 plus 0136, 02 sensor malfunction.

Codes cleared I take for a short blast, revving through the gears.

Runs perfect, codes not returned. Currently on 46,000 miles.

Did anyone come up with a definitive answer ? I am just wondering did I inadvertently do something when revving it hard and curing the 'phonic wheel' issue ?

Thanks

Hello all,

my Wife’s 2013 1.2 Ka kept getting a misfire and cutting out, local Ford garage said it could be the PCU £1,000 and another £104 to program but no guarantee that it would fix it….

I fitted a new 690Ah battery (as hers is the auto stop start model) and that has cured the misfires. It’s like driving a new car again.

hope this might help others in same predicament.

Well the mis-fire on the KA has come back randomly.

It had a new battery just before I bought car, receipt supplied. But as Jimfella suggests it worth checking it the right one.

Looking at the link it looks like the knock sensor is at the front of the engine RHS looking from the front. I am in the right area ?

Also a few have mentioned cam-belt changes, mine also. Could it be a missed tooth ?

And finally I note most issues are cars belonging to relatives ? I have a possible cure to all.  🤔😁

Yep, Wife's KA having same issues. Usual suspects have been changed as above, with no improvement.

Someone has mentioned crank sensor. Anyone changed this yet ?

Worst fault is an intermittent fault. At least if it just broke we would have something to work on !
