peugeot 206 misfire problem

Friends, I haven't been there for a year. There is no master. It doesn't let you down like that. You can continue the cycle when you think about it. I went to many masters for this, it didn't get better. the oxygen sensor was changed, it did not improve. the crankshaft was changed, it did not improve. the spark plug did not change. The coil changed me, it did not improve. The gasoline sensor changed, it did not improve, the brain was not checked with a throttle, it did not change Everything else was done. Do you have such a plot that you encountered?

If it does both gasoline and LPG, have the ignition system checked. If the problem is not resolved, have the knock sensor checked. You need to make sure of them.
