from the back it sounds like its caming or like a wrx exauhst sound

[m.j.h]

Dead plug or coil pack

Injector stuck shut

No compression on one cylinder

If you can, take the cover off from on top of the coil packs and with everything else back together run the engine and unplug one coil at a time if the motor runs rougher plug it back in and move to the next one. When you unplug a coil and it makes no difference to how the motor runs you have found which cylinder is giving you the problem

Or you could pull all the plugs out and compression test the motor first up to you

just checked the plugs they look like theve never been changed thanks for the heads up ill change them 1st and hope it goes away THANKS MATE

if the plugs dont fix it, then your coilpacks are to blame.

But 99.99% its your spark plugs
