I could be wrong, but I was under the impression that the engine management system took into account several inputs other than throttle position to set the amount of fuel injected.

I'll admit to not know a whole bunch about this but I'm going to start learning.

Seems like the O2 sensor has some say, as well as engine temperature & such to regulate the fuel. So I was figuring the O2 sensor input would take into account a clogged filter situation and reduce the amount of fuel at a given throttle position to maintain the ~15:1 air to fuel ratio keeping the engine operating at close to peak efficiency.

Thems engines is smart I thought....am I giving the ECM too much credit? Or is it even more complicated than I think already?

Thanks for the good question, lets all learn something together here.
