I'm roughly familiar with many things under the hood, but not too sure about this one:
I've been trying to get my car cleaned up and better with the smog stuff, and have put a new catalytic converter on, changed oil, run detergents, etc. It's having a good effect, as my HC and CO is way down to near nothing, but my NOX is still a bit over the margin.
I'm told by my mechanic that this can be reduced by getting the engine to run cooler.
Right now, he did retard the timing to get the emissions a bit better, but with the new catalyst I'm thinking I should have some latitude for adjustment if needed... ergo my my question --- will the engine run cooler (and possibly have far less NOX) if I bring the timing back closer to normal?
