Help with new codes 82,94,44

[krafty]

I ran a scan on my car last night. I got code 82 w/KOEO test which says air manegment 1 fail. I got codes 94&44 w/KOER test which say thermoactor left and right sides. I took off the TAB & TAD solenoids and the housings were split open. The question is will these two solenoids cause the car to idle poor and run rich. I have already changed the O2 sensors and adjusted the TPS. Also I sprayed carb cleaner around the intake area and it smoothed out a second or two, does this mean the upper inatke gasket needs replacing?

Im going through the exact same thing with my car right now...and i got the exact same codes. For me i think the problem is that i am missing the two vac lines that go to the two check valves on the smog pump lines....then i get a code from each side of the motor...one from each head. Because there is an air tube going to the back of each head and comming from the smog pump through those check valves that arent working...i think it was throwin those codes. Im just going to rip the smog pump off anyways....but i think that is my solution to those codes. You mentioned the TAB and TAD solenoids...im not sure what those are to be honest with you....but see if what im saying makes sense in your situation...check all you vac lines and egr stuff. good luck man

Codes 94 & 44 - Check vacuum lines for leaks, & cracks. Disconnect the big hose from smog pump: with the engine running you should feel air output. Reconnect the smog pump hose & apply vacuum to the first vacuum controlled valve: Its purpose is to either dump the pump's output to the atmosphere or pass it to the next valve. The next vacuum controlled valve directs the air to either the cylinder heads when the engine is cold or to the catalytic converter when the engine is warm. Disconnect the big hoses from the back side of the vacuum controlled valve and start the engine. Apply vacuum to the valve and see if the airflow changes from one hose to the next.
The two electrical controlled vacuum valves mounted on the rear of the passenger side wheelwell turn the vacuum on & off under computer control. Check to see that both valves have +12 volts on the red wire. Then ground the white/red wire and the first solenoid should open and pass vacuum. Do the same thing to the light green/black wire on the second solenoid and it should open and pass vacuum.

Remember that the computer does not source any power, but provides the ground necessary to complete the circuit. That means one side of the circuit will always be hot, and the other side will go to ground or below 1 volt as the computer switches on that circuit.
