Car does have fogs, but they currently work as they should. I do not think it is for the fogs. I appreciate the responseandrewclaus wrote: ↑Mon Nov 04, 2019 5:05 pm Looks like the fog light connector. If your car doesn't have fogs, it may be an unused extra on the harness. There may be one on the other side too.
Thanks. I drive this car almost daily so I'm trying to fix all the problems asap
Thanks a ton! Is yours also a GT submodel? I havent looked under the hood with these pictures yet, because its 22 degrees in Texas, which is basically hell. Ive spent plenty of time looking under the hood for this stuff but Ill check on that brown solenoid. The connector is ziptied up close to the positive battery wiring. close to the terminal. As for the vaccuum line that went to the backside/bottom of the stock airbox that goes to the nipple on the col air intake, where does the hose start? theres a nipple, but it is capped off.zbyers wrote: ↑Tue Nov 12, 2019 4:20 am
There is no changes to this vacuum set up from the stock air box, to installing the aftermarket cold air intake. There was a vacuum line that was on the backside/bottom of the stock airbox; that should now go onto the nipple sticking off the cold air intake.
The wiring for the brown solenoid is bundled in with either the positive or negative battery wiring. The solenoid itself is either pushed back towards the firewall near the first solenoid I picture. As this isn't plugged in for you, i can suspect that being part of your issue.
One of the aforementioned removed vacuum lines ran to this spot just above the throttle body. Simple cap it off, and you will be fine... Zip tie was so I could identify it if I need to look for it in the future.

The 04 GT is pretty similar to the 05, actually as there is also the smog pump. The 03 GT is the bigger difference (yet better since it has no smog pump!)
The P0171 code is typical of a vacuum leak related to the intake system in most cases. If it's not due to the installation of the cold air intake, it is possible it's the intake manifold gasket. That gasket isn't as big of an issue on the 2ZZ,
As an alternative, if you want to make the car more fun, you can try and find another 05 GT ECU and send it to R9K Tuning and have them put a tune on it.
A good experiment if you wanna help me brainstorm would be to unplug your vacuum switching valve and see if a code comes up. Just to see if the same results happen
