Well I finally got my car running and had time to install my SAFC2. Install was straight forward and easy. My question is regarding the throttle readings. When I first had it installed and turn the ignition to the ON position the throttle readings read 4.4-4.6% when the car was off. Later that day I did the same thing and the throttle reading was 0%. Now again it is stuck at 4.4-4.6% with the car off. Is this due to sticking throttle plates? Throttle cable being too tight?

here are some pix I snapped of the install.

I had the same problem. Warm the car up fully, at idle, go to the main screen > ETC > Sensor Check. Verify that the TPS voltage is 1volt. If not, remove intercooler and adjust TPS screw until the TPS voltage is 1volt.

Thanks for the suggestion. I will try that out. Anybody else got any ideas?

TurboIIRyan got it right on the money... adjust the TPS

Cool. The TPS must have gotten misadjusted after taking off my UIM like 20 times.

The throttle's closed position is controlled by the thermowax. When the engine's cold the throttle will be held slightly open, and it closes when the engine warms up. When you do the TPS voltage test Ryan suggested, make sure the engine is fully warmed up (i.e. after a drive). If that's okay, then don't worry about what it says when cold.

Well I just got back from driving and after it's warmed up the throttle will read 0% if the car is running or not. I'll still check my TPS when I have the chance. Thanks for the help.
