Re: 85 Toy PU, 22RE, 4x4, auto, extra cab, 140k miles, one owner.

After setting my idle speed I ended up with a "rich" odor from the exhaust gases.

Also, in testing my Throttle Position Sensor(TPS) some measurements and procedures failed to match that described in my "85 Toyota Pickup & 4Runner Repair Manual."

Note: My Repair Manual is identical to what is referred to on this site as a FSM (Field Service Manual?) and I have downloaded from this site, although I could not find from where when I looked today. The FSM file downloaded as "toyota4runner.pdf."

The specifics of my idle resetting were:
After setting the "throttle stop screw" (TSS) at 1/4 turn after touching, and setting the idle at 750rpm, I got this "rich" odor from the exhaust gases.

When testing my TPS, between the IDLE and E(2) contacts, my FSM (page FI-62) says that after setting the TSS at 1/4 turn, after contact, there is supposed to be a 'deflection" point from continuity to no-continuity when changing between thickness gauges from one of 0.57 mm to one of 0.85 mm.

Note: Page FI-62 of the FSM is approximately page 229 of my pdf file. (out of a total of 1025 pages)

The deflection point on my TPS occurs at about 1/16th turn of the TSS (after contact) (1/16th turn is as best I can estimate) and without using any thickness gauge.

Also when testing the TPS between the IDLE and E(2) contacts, and prior to the deflection point, I measured resistances from 7K to 13K ohms. The FSM calls for "less than 2.3K ohms."

Note: I can only perform this deflection test with the TSS just barely touching, or I can not detect the deflection point. i.e. all measurements produce no-continuity.

At this point I have adjusted the TSS at approx. 1/16th turn and the idle at 750rpm and get a slightly rich odor. My concern is that I may get whip-sawed at my next smog test.

Any comments on:
1) smog test?
2) testing procedure?
3) path forward?

tks...
