Intermittent misfire problem on 206 roads

As I was walking on the straight road today, the engine seemed to be blocked 3 times in 2 hours. The other day I put injector cleaner in the vehicle. Could it have originated from him?

Friends have no idea?

Does the tachometer go up and down towards 0? Does it happen when you cut your foot off the gas? if this happened to me it was caused by idling valve I changed it my problem got better

makes injector cleaner. The carbones that are discharged from the engine may cause occasional blockages. use a high speed vehicle for a while. Don't take it to the master. It enters the spark plugs from the ignition coil and changes to the idling engine. fixed by experience
