Hi, i took a 350 out for a test drive the other day. The abs/stability/traction lights were lit but the dealer knew about this (abs sensor faulty) however half way back the engine started mis firing badly between 500-4500 revs, bogging down, spluttering and would not idle without cutting out, although if you slipped it into neutral gave it some, it seemed to clear its throat and behave ok at high revs.
Obviously the dealer was a peed off to say the least that id broke the car! and i was too because it was a nice example.
Hes going to get it sorted and call me next week, in the mean time, any ideas of what it could be? I was thinking along the lines of maf sensor?
