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.

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?
2000 Celica GTS 'slowest gts evar'1998 Mazda 626 FS-DE/CD4-E
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?
DOORY MCFLYhttp://www.6gc.net/forums/uploads/av-50000...time=1408581712
Yes, pressure sensor. What's the code set?

The engine light, what's the code?

Not sure I don't have a scanner on me. I'm guessing running rich?
DOORY MCFLYhttp://www.6gc.net/forums/uploads/av-50000...time=1408581712
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.
2000 Celica GTS 'slowest gts evar'1998 Mazda 626 FS-DE/CD4-E
I will look into that asap

http://www.6gc.net/howto/determine_check_engine_light_codesCount the flashes and get back to us so we can single it out.

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.

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?
2000 Celica GTS 'slowest gts evar'1998 Mazda 626 FS-DE/CD4-E
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

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.
2000 Celica GTS 'slowest gts evar'1998 Mazda 626 FS-DE/CD4-E
Wouldn't turning the corrections off on the safc neo be the same as juming the wire?
DOORY MCFLYhttp://www.6gc.net/forums/uploads/av-50000...time=1408581712
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!
2000 Celica GTS 'slowest gts evar'1998 Mazda 626 FS-DE/CD4-E
The settings are right and I hooked it up myself. When I turn the corrections off the rpm go from 2000 to 1300 rpm. So it is doing something. I don't know what the fuel trim setting should be set at pre 1000 rpm. Their just stock injectors and I cleaned them before they went in.

It SHOULD be doing nothing at idle, AFC's are made for ONLY open loop full throttle kind of operation, not to control fuel at idle and low throttle. The computer will adjust fuel trims accordingly and wipe out whatever the AFC is trying to do in closed loop. If your settings are affecting idle then something is set wrong, you need to get back to basics.

So their is two connectors on the Celica TB and the 1mz Camry TB only has the one conector. What's the white block under the Celica TB that The other connector plugs into?
On the other hand The coolant line on the back of the 1mz TB is kinked and this could be a reason that it's ideling roughly, plus their is most likely a vacuum leak somewhere.

Post a photo of the part in question.

That's the idle speed motor, it controls the idle speed by bypassing air past the throttle plate.
2000 Celica GTS 'slowest gts evar'1998 Mazda 626 FS-DE/CD4-E
So it would be okay if it wasn't plugged in because the 1mz throttle body I have does not have a plug for the coolant sensor. I'm thinking of going and getting the TB with the idle speed motor on it. What do you think?

Can you bolt on an original 5S throttle body and plug everything in and see how it runs? You need an idle speed motor, throttle position, and coolant temp sensor for the car to run and idle correctly.
2000 Celica GTS 'slowest gts evar'1998 Mazda 626 FS-DE/CD4-E
No, not with out removing the new intake manifold and installing the old one. I saw one last time i was at the junk yard with the coolant motor on it. So I'm going tomorrow morning to get it and have another look at the vacuum lines on the 5s motor that is at the junk yard too.
DOORY MCFLYhttp://www.6gc.net/forums/uploads/av-50000...time=1408581712
It sounds like the throttle body is the problem then if it doesn't have an idle speed motor on it.
