I have random misfire on cold startup and p0171, I did have the throttle body wire disconnected to clen the the throttle body. I've cleaned the MAF, replaced the O2 sensor, replaced the coil packs and went through the vacuum system. Can anyone help.

 

Have you cleared the code? And iirc 0171 is maf. But it could be the map causing the maf to act up

 

Thanks
