Hello, this never ending problem with fabia seems to be more problematic with me and i never found the real solution to it. i have

1.4mpi 50kw fabia 1 and im hopeless

It started with sounding like using only 3 valves, sort of fixed when i filled with higher octane gas but still sounds like misfiring aaand when warm...it stops if idle, i changed

Sensors-coolant, camshaft pos., 

Checked the brake servo hose, sparks injectors swaped, flexpipe (it was litterally dead) 

Cleaned the throttle body multiple times even if clean

Changed the hose from it to fuel breather

I did everything i found on these forums nothing helps 

Only thing i havent changed yet is the breather itself, could that be it ?

 

When was the car built, and how many km has it covered?

Has the fuel filter ever been changed, do you know?

 

Uuh 2000y. 262xxx km and yes also that one was changed let me add that up

Edit: found out i cant edit original post

Maybe check cylinder compressions?

Thats the next thing im planning on doing 

But i hope the pressure will be ok. If by any chance its okay is there another thing to get checked ? 

Coil pack?

Isnt coilpack for diesel ?
