Question type: Maintenance & Repair

My 2000 Mitsubishi Montero sport
starts and runs for about 4 minutes
and then it bogs out and then some
smoke comes from the bottom of the
engine and hits the exhaust this all
happened when I cut my wires
because I needed the battery quick
and when I connected the wires back
to the new battery I might have done it
the wrong way ever since then it starts
drives for a little bit but then bogs out
like I'm running out of gas and then
eventually turns off please help me out

If the wires for the battery are reversed it probably would not start as the brain would be fried. But easy to check, the positive wire from battery would go to the fuse box and another one to the starter. But in your case it sounds like a clogged catalytic converter. If it starts and dies wait 15 minutes and if it starts againonly to die in a few minutes it's going to be the converter. Remove the o2 sensor bank 1 sensor 1 and allow exhaust to come out the opening. If it starts and stays on then you know you need a new converter. Good luck
