Slow Acceleration when engine is cold from idle

Hey guys,

I'm back and I replaced the Boost Bypass Solenoid, the MAF, and the EGR Purge canister but I'm still having issue with accelerating from idle when the engine is cold. The check engine light is still on with the same issues, Could the issue be the Coolant Temp Sensor or an O2 sensor about to crap out on me?

if you unplug the maf does it run better?

check the wires to the plug to the maf for cracks or any bare wire showing, a bad wire will cause the same code.
 
if the wires look ok, then check all the fuses as well, in the car and under the hood, one of them does power the maf. so ive read here, never had to find it myself yet.
 


those pics dont say anything.

you need to physically take the plug off the maf, top of the TB, and bend the plug end back look for cracks or bare wire showing, also check your fuse box for blown fuses.

un wrap the wires, look at each one.
 
I found the emissions fuse broken and replaced it. When I take the car out next I'll see if the issue has gone away.
