I Need some help, I think i messed up Options

Hey, so I was getting ready to show my car to a buyer and thought maybe I should test drive and all beforehand. After driving for a few mins, I pull out my SAFC2 and go through the categories. I go to car select and it asks the cylinder and its set at 4 and the Up arrow, but I accidentally changed it and it went to down and then the two stars, this is all while the car is at idle. When it changed to the down, the car started to bog down and the idle got rough, I immediately changed it back to Up and exit the screen back to the main menu.

I don't know if what happened after was the cause of my stupidity, but the car started to idle really rough and low to the point where it feels like its stalling, then the car stalled. When I restarted the car back up the idle was rough and low and felt like it was going to stall. I press on the gas and it would bog and then stall. I look at my boost gauge and there seems to be a vacuum leak or something because it's reading around 10, usually it's at 21. I look under the hood, and i smell fuel and see some fumes coming from around the IM area. I think its the fuel injector area and near the throttle body area as well. I am really not sure what the problem is. I now have a CEL and when i drive, i can hear a big vacuum leak, kinda sounds like im spooling and if i let go i hear either my wastegate or a psssh sound. Anyone have any idea what this can be? I am confused and really upset because I was just about to sell this and this happens.

Cliff: My car idles rough, low rpm idle, stalls at times when i press the gas, CEL is on, car sounds like a constant BOV or boost leak while driving. Couldn't find any vacuum leak anywhere.

The swap was done by the previous owner and some members of this site like presure and batman along with some others..

The car was running perfect a few minutes before and didn't have any signs of problems.

Oh this is my first time dealing with obd1 CELs..so i would just stick a paper clip in te and e1 and count the number of flashes the CEL has? That's pretty easy..is there a code list somewhere to tell what it is from the number of flashes?
