I am still getting a rough/misfire idle at cold start. I unplugged the maf last night, the engine was already warm and took the car out (i think) it pulled better however I got a huge hesitation at full boost.
This mornings cold start with no MAF was fine, smooth idle and power seems great.
The only thing is the MAF is new 5 months old if that? Does anyone have a pic of the MAF fitted, I am not sure if I installed it back to front?
