as in they touch together. you want to drain any stored memory. sometimes, it's a couple seconds or even minutes, but i've seen more and 1/2 hour should do it.

For sure. I've already done it twice. Once two years ago, I used a universal (knowing no better) that went out in a few thousand miles, throwing a 25 and a 26. Put in a Denso, cleared it right up.
That was a year ago, if I remember correctly. I haven't put but maybe 3500 miles since then... maybe.
So, could a bad head gasket, bad cat or other bad sensors have caused the rich condition that shot my MPG and then in turn ruined the new O2? I suppose it's worth the sixty bucks to find out.

You do not have to remove your battery terminals to clear you current codes, all you need to do is find the fuse box (long rectangle one parallel to battery) and just pull all the small colored fuses one at a time and put them right back.
For testing for a leaky fuel injector, you may need to find a mechanic who works on Toyota's to check.

If anyone is interested, I found the source of the surging high idle. Still determining if it fixed the rich condition; I'm going to mark my mpg off this next tank of gas to see.
It was a clogged coolant hose from the intake manifold to the TB, rendering whatever idle control in the TB ineffective. The PO had used green coolant, not changed it (ever?) and the entire cooling system was full of rusty gunk. This particular little hose was the last remnant of that.
After all that headache and money, it was a $.90 hose.

Otherwise, hows the car running?
