Hey guys here my problem swap in 1996 tracker 1600 16v with 28,000 miles  obd 2 in my 88 samurai  is poping  throw my exhaust acting like its missing only at idle to about 3000 rpm then clears up at high rpm. read codes and it has only has 1 it said random missfire unknow  any ideas other then having tight exhaust valves ?? it has new plugs cap wire!

Check the firing order, and the cap and rotor, I got a melted
rotor once, thought it was due to the turbo pumping hot air into
the distributor housing, but who knows.

1,3,4,2 firing order and the distributor turns Counter Clock Wise, not
clockwise like the 8V engines
