So.. it's been a weird week for my mom's es300, 1 wheel kept losing air, went to the tire shop to get it checked, and they couldn't find anything.. went to another shop same problem.. I'm afraid my mom might have driven with no air in the tire and driven around causing an issue with the wheel sensor maybe? cause now the ABS light blinks intermittently..

Also had radiator cap was leaking, so I had to replace that... anyways.. I was planning on giving it new hoses all around, and such this spring break..

I remembered taking off that intake mani was a royal pain on her 2ES, but I figure it's something I have to do cause now there's also a CEL for the rear o2 or afr sensor I believe.. or do i not have to pull the intake mani for the rear sensor?

Anyways.. If I'm pulling the intake mani off, what should I replace besides the rear plugs? Does the 3ES have that annoying coolant hose also?
Knock sensors and knock sensor harness? Oil control valves, intake manifold gasket, did I miss anything?

Thanks guys
