[V6-12v] Throttle body gasket fix

I surfed Nathan White's site yesterday and found a really useful tip on how
to fix that pesky throttle body rubber doughnut gasket thing. Here's the link:
Essentially, you cut an 11 inch piece of RJ-11 cord (regular flat phone
cord) and stuff it into the groove in the rubber doughnut. After this 5-10
minute fix, the gasket seals correctly against the plenum and the car idles
a lot smoother.
I think Nathan does it without removing the doughnut from the throttle
body, but I went ahead and removed it. It makes the stuffing go a bit
easier. I have done two things which have had an impact on the slightly
rough idle: Changed fuel filter, and NW's doughnut stuffing trick. I think
both gave about the same improvement on the idle.
While on the small jobs, I took the MAF sensor out and cleaned it. Some
electrical contact cleaner took most of the black build-up off, a half hour
in an ultrasonic bath with IPA (isopropyl alcohol) did the rest. Now I just
need to reset the ECU and I'll be all set for a better running car with new
and improved fuel economy (hopefully).
