bought a 2007 ridgeline, has 150k miles or thereabouts. Been getting check engine light repeated often over the course of the winter and till now. But the engine runs fine no missing or performance issue. DTC stored have been P0301 through P0306, and P0300. So I figured it was likely the EGR valve, especially after seeing youtube of the 3.5L being known for clogged egr port in intake manifold, with the fix being Standard Motor Products EGR repair kit F23001 and B22001 with the drill bit and stainless sleeve.
got intake manifold off and it looks like this, the egr port is nothing like that in videos. This port is about 7/8" in diameter.
anyone familiar with this?
did previous owner(s) install an aftermarket intake as a fix to the clogged egr on oem intake?
i don't know what Keihin is, but there are stickers with that on various places on the engine so i assume that's all oem, like delco is to GM ?
Have already got both front O2 sensors replaced.
because I'm this far in, going to put a new EGR valve on it from autozone.
Was going to do a fuel purge valve (sits driver's side just aft of throttle body ? ) as well but have to mail order it, but I can get at it with the intake reinstalled.
Are there any other basic parts that should be replaced, that are known problems after 100k miles on the 3.5L engine?
and i don't see a mass air flow sensor, can someone do a quick brain dump for me on all the major engine controls on this type of engine and how it runs, thanks.
