This is my friends car and he is having problems and we are trying to fix it. car has a horribly ruff idle, In the video when it bogs down then rev's up is when i try to give it gas. If it gets above like 3k i can rev it fine in-till it starts to bog out again. You can see the ruff idle from the camera shaking. at the end i try revving it up and eventually it dies

I'm stumped and I've tried alot of things

New fuel pump,fuel filter,spark plugs,cap/rotor

Any codes? Was the MPFI swap done before or during?

No cel

 

Car seem's to be backfiring threw the intake

 

Sounds like a timing issue to me
