The MAF may be my problem as this all started after I cleaned it with TB cleaner. I will get some electronic parts cleaner and do it again. Looks like the sensor requires a special tool for removal - sort of a hollow torx. What is that? Will I have to replace the gasket underneath it?
If that doesn't work I'll clean the EGR.
With 72K mi. it seems a little early for O2 sensors to fail - especially two at the same time. Someone told me that if car has ever run out of gas those sensors could be damaged. True?
Thanks a bunch for the advice. Really appreciate it.
