So I been Working on my Xa for a lil bit Now doing lil things here and there Messing with it And recently installed alternator and battery and ignition coils but. At 3000 rpms the engine starts to shake and starts to bog out or cutt out any suggestions on what it could be ?

Before and what it looks like now

 

Any chance it's thrown any CELs? Could also be fuel related...might want to check fuel pressure and run some injector cleaner through it as that won't hurt anything.

 

I replaced the battery but it's still doing. So next will be the fuel pressure
