Hello guys, I'm a new here and i have a problem with the engine.

Only 3 cylinder is working and feels like that cylinder number 4 is not working as whel, i have allready check water and oil is not using oil and water as well. But when I'm driving normal 80km feels like 4 cylinder is working, and i check the sparking, spark all 4 and fuel rail is also checked no problem, what can k do now ?

check the compression ..maybe new plugs worth a try

As above, compression test will tell you alot.

If it's okay, then the plugs should be checked and changed if they are not good. And also the coil should be checked as these can fail and have this effect.

Also coil packs can go dodgey

Yes, do a compression test. This will tell you what the next thing to check is.

Thanks guys. I have allready change new plugs and, i check all the plugs hole when i take the spark plug out it come the same air pressure or compression same at each hole. So maybe it can be the coil pack the orange one or the black one ? Because the coil packs from the orange lne each hole got good sparks
