Check injection / check esp megane III tce 130

Check injection and check esp light comes on for like 2 seconds (SOMETIMES)when engine starts. Then engine light flashes, sometimes it shows anti-pollution error too. You can also hear wierd pop offs from exhaust, the problem is not coil, not injector, not cables, still diagnostic it shows misfire at cylinder 4. After all lights are off the engine and car runs perfect! No cut offs or anything. tce 130 megane III 2008 1.4 53000 KM
