Recently I was getting error codes for my upstream and downstream o2 sensors and EGR valve. I replaced the o2's and the EGR valve started working. Once that happened my Mass Air Flow Sensor showed up bad. I assume this was an after market part becasue when I replaced it the new one had honey comb vents (i assume it restricts air flow more.) The old MAF sensor was wide open. the check engine light was still on after replace the MAF sensor so I reset the computer and now I get an error saying my ECM is bad. The car still runs good and seems to have plenty of power.
What could cause this ECM error to display?
