Technical Error code p130a - cylinder misfire

[dj8]

Hi all, the other week my car engine light came on so I took it to be checked. The garage got following error codes p130a p0301, it seems cylinder 1 misfiring. The misfire only seems to happen when idle and engine is warm. Driving at speed seems fine. My mechanic has checked coil, spark plugs, Injectors and pressure which all seem fine. Car is only 4 years old 30k miles and is petrol 1.4 turbo. The other thing to note is when engine light comes on I also get "stop and start disconnected" message. Any ideas or experience that anyone has with this much appreciated.

Can't say I've seen any real reports of misfires on here

It could be worth swapping the coil packs on cylinder 1 to one of the other cylinders see if your random misfire moves to this other cylinder

Hi Chris, mechanic tried this but didn't help.

If the car is multiair, that may be the problem. It is very sensitive to engine oil

It's a 1.4 t-jet

p130 a means that the computer turns off the injector of the first cylinder due to too much misfire. Check the socket on the injector itself for a bad contact, also on the ECU side there may still be a bad contact.

Thanks will pass onto my mechanic to check. Attached are the error codes we got if like take a look.

I know he swapped two injectors around to see if error moved to another cylinder but it didn't error still showed on cylinder 1

Did the mechanic confirm that the engine's not overheating or the headgasket is not leaking?

He didn't say, but he did think unlikely to be a mechanical issue due to only 30k miles and only just turned 4 years. He's a good experienced mechanic I've known for many years so think he would spot what you mention. If was overheating wouldn't it be an issue driving at 50mph. Issue only seems when idle for 30 secs or so and engine is warm. Doesn't have the problem from a cold start.

Il ne l'a pas dit, mais il pensait qu'il était peu probable qu'il s'agisse d'un problème mécanique en raison de seulement 30 000 milles et d'un tout juste 4 ans. C'est un bon mécanicien expérimenté que je connais depuis de nombreuses années, alors je pense qu'il repérerait ce que vous mentionnez. S'il y avait une surchauffe, cela ne poserait-il pas un problème de conduire à 50 mph. Le problème n'apparaît qu'au ralenti pendant environ 30 secondes et que le moteur est chaud. Il n'y a pas de problème de démarrage à froid.

Bonjour
Comment as-tu résolu le problème?
J'ai le même problème et il n'est toujours pas résolu
