Still have idle problem. Removed AWS
the car is an 87 NA. I have already removed the AWS sensor but it still revs to around 4000 rpm's when started. This is a video i just made about it to give everyone a better idea of what i am talking about.

yeah sorry i removed the solenoid. I did not cap off the lines, but i connected the hose straight from one side to another. Basically i just removed the solenoid and connected the hose like it was never there. Tomorrow morning i will try capping off both separately to see what happens.

ok well i removed the single hose and capped both ends that it was connected to. It doesnt rev to 4000 and stay anymore, but now it starts up goes to 3000 then slowly goes down until it dies. Could i still have a vacuum leak? Any ideas?

I was just asking if you did anything to these wires as opposed to how to do anything. Don't jumper the wires together or the ECU will interpret that as a signal to initiate the high rev to 3000 rpm all the time. Leaving them connected to the sensor will leave the decision to the sensor to initiate or not and disconnecting both wires from sensor and taping them off turns off the signal completely.

You could have saved yourself some time and just unplugged the AWS. But keep in mind that it only plays a small role in the 3k RPM startup. The BAC is the other air delivery component, but don't go removing it. That temp switch at the bottom of the radiator can be the work-around you're looking for, but it's not going to do a thing for the vacuum/metered air leak you likely created. If the engine revs up then stalls, it's a good bet you have a leak. Check the areas you messed with; especially whatever you capped off. The big black intake duct also likes to leak at the connection points.

Before you removed the air bypass solenoid..........would the car idle once it was fully warmed up?
If the RX is started with the clutch in and the shifter in gear..........there should be NO fast idle upon startup at all. So it does sound a bit like there is an opening in the intake somewhere. Like maybe the half inch hose on the bottom of the large black intake duct just prior to the throttle body?? The one that is on the bottom of that black duct and can swivel around a bit?

Well i unplugged the sensor that satch was talking about with no change. I have tried starting in gear and that doesnt do anything either. The car will not idle at all. It starts up revs to 3000 rpm then after about ten seconds it just dies. I can keep it alive by revving it a little bit but if i leave it alone and dont press the accelerator every now and then it dies. I have thoroughly checked for vacuum leaks and cannot find any. Could i have a bigger problem here?

You still have a large vacuum leak somewhere. One solution to finding all your leaks would be to pressure test the entire induction system. You can make a pressure tester with plumbing parts from home depot.

Sorry for the late update but here is what i did to fix it.
I removed all of the emissions control system and blocked off all vacuum hoses. I also made custom aluminum plates to block off certain areas. I followed these instructions to get everything done.

These are really good instructions btw so if anyone plans on doing it, this is a must have.
Now i have just found out that i have a bad AFM (i must have tested it wrong the first two times) but with it unplugged she will start right up and idle perfectly. A new one is on the way so hopefully she will be drivable within the week.
