RICH Idle? - 3000GT/Stealth International Message Center

Drweldin · 04-14-2008, 04:20 PM

Please vote and/or post if you experience a "Rich" idle. (or don't for that matter).
We'll make the following assumptions:
1) You have larger than stock injectors
2) Piggyback fuel control
3) WARM idle
4) OBD 1
5) "Rich" = 11.0-13.0 AFR, or NB won't cycle

If answering "yes" at all, please list injector type & size, and fuel controller!
Thanks

YES - 560 Evo injectors, MAFT Gen 2 (did same with SAFC 2)

Same here :

Evo 560's, SAFCII,

"Rich" = 12.0-13.0 AFR, or NB won't cycle, but sometimes it idles at 14.6 for a while .... I'm sure it has to do with the ISC and stock Ecu Control. The car is just starving for air... Come on guys, you with rich Idle, chime in !

I thought I was the only one ...

PSnewbie · 04-14-2008, 04:40 PM

Umm, I voted for some reason. don't mine me. but I do idle rich anyway.....

DoctorDex · 04-14-2008, 04:52 PM

I put Yes, but mine only idles rich on occasion, ie. a few times a month and it usually fixes itself after 1 min or so.

PTE 580's, SAFCII, MAFTranslator.

Another thing I forgot to mention: It only seems to idle rich after spirited driving or in hot weather.

I vote even though I have a '94, but mine idles at stioch.

PTE 680cc, Emanage blue and maft.

I have the the maft at zero correction so it is basically just a translator.

I'm using 660s and maftpro, I get a 14-14.9 idle depending on the weather, and how warmed up the car is
