Help!! Celica is runnig rich at idle, Celica is up and running today. Options

[doory100]

Celica is up and running today. It's running super rich especially at idle. Any idea what may be the problem? My afr guage is buried at 10 and its burning black soot out the tail pipe.. It drives pretty good but it's jumpy when I let off the accelerator. I have a apexi neo safc installed. any links on how to set this up?

Coolant temp sensor and primary O2 sensor are responsible for managing the air/fuel ratio.

[doory100]

is the primary o2 sensor, the one with the two bolts and the one wire. that one is installed and plugged in. and the wide band is installed after this one. The other o2 sensor is not installed.
Also, Where is the coolant temp sensor located?

Is the engine light on? What's the AFC set to? Speed density? Does it have any corrections entered?

[doory100]

yes the engine light is on. It was set to zero. but i turned the corrections off, It was still the same just idled abit lower with the corrections off. The gt celica is what sensor type. I think its a pressure sensor, is that correct?

[Bitter]

Yes, pressure sensor. What's the code set?

[doory100]

Code set?

[Bitter]

The engine light, what's the code?

[doory100]

Not sure I don't have a scanner on me. I'm guessing running rich?

[Bitter]

Don't guess, there could be a code set for the cause of it running rich. Rich is the symptom of something wrong, you need to find the cause of it.

[doory100]

I will look into that asap

Count the flashes and get back to us so we can single it out.

[doory100]

Code: 25 and 31

[Box]

25 is air/fuel ratio lean and 31 is air flow meter signal/vacuum sensor signal. Given your readout and etc... your MAP sensor is frucking things up.

[doory100]

Ok I did the test where you clear the code and then I jumped te2 and e1 with a paper clip drove until the light came on and got codes 27 and 71. 71 I know because I capped off the egr because of the custom intake manifold.. I have to figure out the vacuum leaks and make sure they are all gone. It seems to run ok well I'm driving and I did get the afr at 14.7 with the apexi neo while on the highway. But it still runs rich at idle and when I decelerate.

Whats your fuel pressure?

[doory100]

I haven't checked the fuel pressure yet I have to do that on Monday after work unless there's a way I can do it without a fuel pressure testing system

[Bitter]

Not that I'm aware of. What's the MAP sensor showing for a reading? If you take the AFC out of the car does it run normally? Just jump the MAP sensor wires back together and it's back to stock, the AFC is only a sensor monitor then.

[doory100]

Wouldn't turning the corrections off on the safc neo be the same as juming the wire?

[Bitter]

It should, unless there's something wrong or some setting you missed or got messed up. Take things out of the equation, KISS: Keep It Simple Stupid!
