need some light shed on my problem please

[hainesz]

ive just bought another mk4 1.8t AGU R32 rep... the problem im having is i noticed the MAF was disconnected and it also has a wire coming out going to earth (this looks like someone has done this) so i plugged it back in and when plugged in the car wont rev over 3.5k it just starts spluttering and back fireing... then disconnect it and it drives fine again...

now what i need to know is what would cause this? is it faulty MAF?
also why did someone earth it out? whys the EML not lighting up when the MAF plug is disconnected?

if anyone can shed some light i would be most greatfull...

It must be mapped mate , i had a subaru that had the maf mapped out

[Wazzzer]

MAF has been disconnected to sell it without it running rough. AGU has no EML or check engine light on the dash

so what do you reckon wazzer... new maf?
