Sr20det rough idle no leaks

[310westslide]

I have a sr20det that started idling rough since yesterday for no reason I checked for boost leaks and any type of leaks and nothing my afr is reading high n low like crazy

MODS:
power fc w/ power fc commander
front mount intercooler
methnol kit
555cc tomei fuel injectors
t28 turbo w/ s15 turbo internals
turbonetics bov
electric fans
Nismo fpr

And some other thing I forgot like intake

possibly the tune on your pfc. how is your vacuum routing? i had a rough idle problem and it turns out my vacuum routing was wrong. double check it and let us know

Okay.. I'm gonna try n find a blueprint for the vacuum routing

check your intake piping to make sure the maf isn't too close to the turbo. i just had the same problem with mine. maf should be at least 18" away.

Looks like CTS, but you never reach what I consider idle rpm.. So maybe you do have a vacuum leak or your idle is to high. It's hard to diagnose like this. If you idle at 1000rpm
and the rpm fluctuates like that it actually masks the problem.

So, if you can cover the BOV outlet up, and or pinch the PVC line on the intake, this would help rule out vacuum leak.

If that does calm it down , but doesn't stop the fluxing then it's probably cts, the ecu thinks the engine is overheating. And is giving you visual and audible warnings.
I did see you are at 74*c, but if the temp sensor is faulty it doesn't matter.
