okay guys. i have a 6-bolt swap + 7-bolt head just done. no random misfiring. all boost leaks just fixed. new exhaust gaskets. brand new o2 sensor. i plugged im my passenger side fan into my front o2 sensor plug by mistake the other day and it made a click noise somewhere and RIGHT after that happened and i put everything where it needed to go i fired it up and my car was dumping fuel bad! Right before i did that with the fan it ran great! now this.

ECU: i had my ecu checked out its fine nothing wrong. also tried different ecu
so thats not the problem.

Boost leak: i just did a blt and its holing the boost i need.

SAFC2: even -50 at idle it doesnt change this dumping fuel.

Exhaust: no leaks just fixed all gaskets and used a snap on smoker.

Im so stumped right now and can not figure this out...what do you think guys...and yes my MAF is plugged in and not bad.
 
like test the o2?

i replaced my old one with a BRAND NEW one and still didnt run better
so i used one from a spare o2 housing that i know works and yet again
didnt run right...

please guys i need this fixed like last week...LOL
