Rich idle fouling plugs misfire

[CSquared]

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.

I just had the same symptoms and mine turned out to be a frayed map sensor wire.

Yeah map is on my list of #### to check if the ecu and safc come back with no difference.

Oh god how I'd love to drop 2k and be done with this bs, but financially out of the question at the moment trying to save for a house.

I don't know if this has been brought up yet, but check your ignitor.

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.
