heres all the problems i have at the moment.... my 2.8 vr is bogging, it misses when i change gears, i can only drive it fast if i hold the gear for a while (almost like it doesnt know what gear its in) it boggs and then drives normal, its started to overheat now but i realized my fans were off, their on now but it still overheats but slower... it also smokes when im standing still and keep the revs up, also smokes when i drive hard and slow down... its more of a lighter smoke than dark... any suggestions please? i am from south africa and my mechanic told me its going to be R12000 to fix...
