Ok. Have you ever replaced the Spool Gasket filter? The VVT could be messing with your timing until everything gets warmed up. I just replaced the whole assemblies at 200k miles on my Crosstour. Huge improvement in engine performance.Brand new maf sensor I swapped it out with an oem due to high mileage reasons egr valve, plugs , air filter , I just swapped out the pcv valve. No codes whatsoever
If your talking about changing your spool gasket..., I see it a cheap maintainace. It's a gasket that usually fails in a dramatic fashion on old high milage v6's anyway. Think of it as staying ahead of a disaster.Don't know that's a job on the Pilot i need to have more evidence to point to that particular part. Not really in the mood to tear half the engine apart to replace an item that may not even need to be replaced . This could also be an o2 sensor going bad .
