SR warmup problems

[s13silvia123]

does anyone ever have problems with their SR when starting their car up.
mine bogs when it starts up cold then after it warms up to 68-75 degrees it runs ok. its pretty warm over here like 80-90 degrees outside and my sr bogs when its cold when starting up around 30-55 degrees.

started doing that when i took my FMIC out to install a push electric fan in the front of the radiator. FMIC was properly installed back on and tightened up so there are no boost leaks.

also running a z32 maf. <------ could it be the problem. never happen when i install the z32 maf. its caliberated with the Power FC to work properly.

check the idle air control valve air regulator valve, it's the black square shaped doohicky. one side is black the other's aluminum, it has a vacuum hose on each end, one goes to the idle air control valve, the other goes on a bung in the intercooler piping before the throttle body. it's job is to allow more air to the iac during cold starts. gl

iacv should do it. that happened to me when I first put in my sr. I also had a vacuum leak (tiny leak) that would close when everything was hot so the car would run fine after warming up but sucked at idle and between shifts when cold (mainly at night around 45-50 degrees).

so if its the IAVC right. i have to clean it and use new vacum lines rite.
