Exclamation Jeep cherokee engines running rough! HELP!

So beforehand it wouldn't start, so I replaced basically everything I could think of.

-Coil
-distributor
-spark plugs
-wires
-Crank position sensor
-TPS
-IAC
-Oil sensor

It starts now but it runs rough as hell, the check engine light is on as well. I get a strong smell of gas coming from the exhaust, and I took a video of the problem! Please help!
Edit: I did notice that my check engine light did start blinking once towards the end of the video, does that mean anything?

Nope no fix! It's still running the same. I took it to the mechanic and he scanned it and said it was the TPS. I replaced the TPS but it came up as defective, so I replaced it AGAIN and it made NO difference. Still have a check engine light and about 10 seconds in it stalls out now. any ideas?

did anyone fix it. I have a 99 Jeep Cherokee limited and it’s doing this. Now it won’t run. Just put new computer in. Does it need to be programmed?
