Clio 182 cylinder 3 misfire

[kenith15]

Im typing on a phone so sorry if this looks weird aha

So, it had a misfire on cylinder 1, at first, I changed the injectors and spark plugs, it then worked fine for a day or so and then it started to misfire again, plugging it in again showed cylinder 3 misfire, i then changed the HT leads and coil pack, with no difference, everything has a spark, the engine just sounds like its not getting enough power and is idling between 700-900, I dont know what else to try, any suggestions?

Is the miss there all the time or just at idle?

Do you own a multimeter?

If you changed injectors/plugs/coil blah I would start having a look at injector wiring, could be a broken wire on one. If you can verify that is not the case then I would crack on with a compression test.

Definitely sounds wiring related. Have you checked all your earth points?
