420A 420a isnt running right

[RAZORTX]

Alright so the car is running a bit weird I just got under the car and found out the crankshaft sensor had a wire cut so I fixed that with some help of one of you guys on the forums now it starts up but it has a very odd idle, and I can't seem to figure it out, and neither can my dad so here's a video of the engine if anyone knows what could be causing this can you let me know? thanks!

First verify if getting spark on all cylinders, then getting fuel into cylinders, then intake air leaks, then compression.

Have you checked the timing too? Might not be bad idea.

Sounds more like one cylinder isn't firing. So check for fuel and spark first.

It's getting fuel, and spark. one time I got it to rev up completely and it was idling at 800-900 rpm I drove it around it around the block it felt like it didn't have much power and it the engine shut off before I got back home so I had to push it back
oh and it's in time
