do not clean the maf sensor you will do more damage to it. it is not fluid related or filter related.

 

If something as simple as the air filter has been that neglected you can bet your butt the 60k spark plug change was never done.
Most people only replace the spark plugs and wires when there is a problem.

 

You are 100% correct Spike. Spark plugs showed up today so I swapped them and the ones I pulled out were definitely the originals. I'm hoping she runs a lot better now.

 

Looks likeSocalrovershop and Rovin4life are probably correct. After swapping out the filter, plugs and o2 sensors the cel came back on with the same code. I called up the dealership and they said they couldn't find any records of the cat being checked/replaced. They told me I have an emissions warranty until 2016/120k so it is headed to the dealership next week to have the cat checked. I'm hoping that is the issue and they get it fixed. Thanks for all of the help!

 

Dealership confirmed this morning the cat does need to be replaced.

 

Thank you for reporting back.

 

I had the similar issue, and ended up replacing the O2 sensors but that wasnt the case. As for now, I wont be worrying about those. After a few times of getting the Chk-Eng Light to continue to appear, my Tech determined it was the MAF, and Air Intake Tube/Hose that were unserviceable and had to be replaced.The MAF because of the K&N Air Filter spray, it ended up damaging the MAF, so I purchased a new one and problem solved for that. As for the Air-Intake Tube/Hose, it had a minor hair-line crack on it, so that was affecting the vehicles performance as well. Upon having that also replaced, the light went away and my RR's being running great ever since. Hope that helps out.
