AFM unplugged or faulty

What else was done to the engine!

If it is smoking black smoke when you hold it at the 1500 rpm limit is is almost certainly a dud AFM. Does it have an oiled pod filter!

Blocked exhaust maybe!

Faulty coil(s)!

sounds like a afm to me aswell. have you checked no intercooler pipes have blown off that will give the same symptoms of a stuffed afm. i would also check the afm wiring
