I developed the ping related to the laughable intake manifold gasket set leaking coolant/oil into a couple combustion chambers creating ping. I replaced all related gaskets that came in the Fel Pro kit. Plugs are all even, now. The two that were wet before the gasket change have now equalized to the others. Showed signs of leaness and the spray bottle steam cleaning I gave them about 1000 miles ago.
Only code I am getting is 186, injector pulse width too high. This only happens during higher load settings particulary when the remaining but greatly reduced ping is audible.
From reading, it seems the MAF elements may need cleaning to remedy a lean condition. My theory is, the PW goes high when the engine begins to ping because of remaining deposits from gasket issue. Or, maybe it just pings because it's lean, due to MAF code, though I'm a bit surprised I'm not getting a MAF specific code.
Thoughts? All of this with 87 octane, I need to smog, been running injector cleaner. I think I can keep the CEL off and pass smog with 92 octane at this point.
