can anyone help i have a X reg 156 jtd, ever since i bought the car it has been very sluggish, not wanting to rev very high. There is a sudden loss of power at about 2500 - 3000rpm, its as if yhe turbo is not kicking in. I have read many posts on the MAF sensor so thought it could possible be that. I disconnected it last week but it made no differnce at all, there wasn t even a light on the dash, do you think the MAF is knackered or do you think it could be something else. Any help would be much appriciated.
