My girl is unwell

[Smangle]

Heya fellow members I have a 200gt model and it not very happy I got it with slipped camshaft pulleys I've checked the engine over and it's getting good compression across the board between 170-175 timing has been checked multiple times genuine tools used to lock the engine I've attached some of the data from diagbox it just will not idle smooth unless I unplug the MAF sensor any help would be greatly appreciated.

Thanks all

Change the MAF sensor these can cause a lumpy idle if faulty
