my ef civic is throwing a code 20 and code 1... it has a pm6.... i just replace the o2 sensor... and tested the EDL which is bad from what the test is showing.... would this make my car run rich and sound like it has a dead cyclender????? i have compression in all cyclnders.... new spark plugs.... car has power over 3000rpm and runs better above that.....

so would a bad EDL make the car run bad?? or what could be causing the motor to run rich????
