2 problems here

How much pressure is normal on a afpr to have?
I bought one from a member a while ago, and now installed it. At idle, it is set to 22

I have a idle problem, can't find any vacuum leaks.
Base timing should be good. I did tdc on 0 and lighted up the notches up top. Spun the motor by hand 2 times, and aligned just right.
Ignition timing may be off some. I couldn't get it right due to the idle fluctuation.
According to tsrm, I checked the tps, and here are my results. I didn't do the feeler gauge. Not sure if you actually need to use that. But in the picture I couldn't tell exactly where it goes. So opted out that.
Vta-e2: .914 ohms
Idl-e2: ol
With throttle wide open:
Vta-e2: 4.56 ohms


Could there be something else I can look at for fluctuating idle?

1) A stock GTE uses Toyota's Type A fuel system. That means 36 psi, a value that falls between the 33-40 psi specified in the TSRM. That pressure is as good a place as any to start.

2) IDL-E2 must be low resistance for the idle speed system to work. Put another way it must be low volts (almost ground) to the ECU. In such a case there won't be a code 51 with the throttle closed.

3) You're confusing ohms for kilo-ohms...

When setting fuel pressure, you also remove vacuum from the AFPR, or check pressure with the engine off by jumpering B+ and FP at the diagnostic block with the engine off. With manifold vacuum it should be lower pressure.

So I also forgot to mention, that I'm running 560 inj and Lexus Afm. Does that matter still on psi?

And I totally didn't see the k before the ohm. Lol

Thanks good to know!
