Vehicle is currently running rich and when I do a cold start the vehicle would feel its about to die a couple of times but its fine once warm up, I have no idea if it's the maf, map, 02 sensor, tps, iacv, or a vacuum leak, I clean everything except for the tps, no check engine lights, I did unplugged the maf while the vehicle is running and still keeps running without it, any ideas?

Here's a couple of links of the cold start

Weird Idle on cold Start

Start Up

 

You should do a boost leak test.

 

Turns out that this hoses was disconnected, not sure if this will fix the running rich problem

 

Car still has the weird rough start up after checking the vacuum hose

 

The weird start up was from the battery where it was only doing 9 cranking amps instead of 400, thats why I had a dead battery each time I attempted the start up, already replace the battery and starts up no problems
