heres the rundown. 88 lx dohc zc pg7 ecu. 3 out of 4 of the cylinders are firing. i've replaced the plugs, wires, cap and rotor and thermostat. i'm pretty new when it comes to hondas, so i need help. it isnt running right. ive checked the ecu and its throwing a 19 at me. great, i have a 5spd car and an auto ecu. could this be a problem?
