No, I enjoyed your descriptions. Thing is I am getting great gas mileage. Last highway trip 22.5 and around town is usually 18. I do have to check more of the vacuum lines, particularly under the engine covers. Also, what have you found with regards to the air spreader/intake rubber grommets. There was a utube that dealt with this intake issue. I also want to be sure no of this is related to the exhaust side or emission air pump system. I did do all four O2 sensors last tune up. I will get the goods and give all this a try, not sure about tackling the vanos seal kit right now. Hopefully it's ok for awhile. I realize 180K on a 2001 is pretty good mileage. BTW, no oil burning or leaking...
