UPDATE 3/7/11

This is an aristo swap single turbo on stock fuel aside from a SAFC. When I got the car started the first day or two it ran like a champ.

The car sat in a garage for the week and when I started it up again it was running in limp mode. Most annoying is that there is no check engine light.

So far I have done the following:
-Replace O2 sensor with oem toyota
-Cleaned the IACV
-Replaced plugs
-Sent ECU off for capacitor service (still out)
-Sent the SAFC off for bench test by apexi (still out)
-Ordered new ECU coolant temp sensor from toyota
-Thinking about pulling injectors for re-test

Any other suggestions?

Loose & flattening vacuum lines were the cause, when I was chasing similar symptoms/issues. Good luck!

Have definitely taken this under advisement. Now that the weather is getting decent again I'll probably just redo all the vacuum lines and call it a day. Thanks for the response man.

How do you use the Honda AEM on the motor? You would have to make a jumper harness or something?

Yeah I was gonna say "civic integra 30-6040"?

$1800 for the supra through the same guy. So I guess unbam.

None the less...

So far driftmotion got back to me on the ECU and said that some of the capacitors looked to be leaking. No guarentee but it's a ray of hope.

Apexi also called me back. Their unit tested fine and they verified my settings to be correct for the application.

Otherwise I'm pretty much SOL until I get those back and plugged in.
