ok i was driving at about 2500rpm and heard a small, not loud, clunk, from somewhere.. and then it all of a sudden started dropping power and felt like it wanted to stall. it runs really rough and spits black smoke out at idle and higher rpms. i drove it home like this and i have to keep the rpms between 1700 and 2000 or it starts to shake(as soon as starts making boost)
my gues is plugs MAF or god forbid the turbo. im going to check them out now, if anyone else has an idea lmk please..
