I know as of late there seems to be countless members with idle problems. Well I'm not sure on this one, but I might have found a solution.
My brothers subi has been running kinda crappy lately and there wasn't an identifiable source. He took it too a garage this morning and this is what they did. The TPS on a subi is adjustable. So they adjusted it until the car was running properly. It was nothing complicated, and just a basic recalibration.
Well I put 2 and 3 together and got 4. Its not quite the same, but close to what they did with my brothers subi.
I looked my my TB and I'm pretty sure our TPS is non-adjustable. BUT guess what is! The little screw in the TB! The the throttle mechanism is attached to throttle cable. So if you adjust this screw to leave the throttle slight more open/closed would this not adjust the idle for the car?
The only problems I'm wondering about is:
1) The screw is double thread? how can you adjust it?
-Double nuts tightened into each other might work.
2) Will this completely mess with the TPS?
3) ECU must have to be reset because the car will have to relearn the idle.
Let me know what you guys think! Cause I have never seen anyone mention adjusting the screw for the idle.
