OBD1 codes need help... 332, 314, 311, 536, 632

Here the codes, 332, 314, 311, 536, 632.

I've already changed the egr valve, and my check engine is still on. Any ideas ?

332= Insufficient EGR valve opening detected
314=AIR system inoperative during KOER(bank 2)
311=AIR system inoperative during KOER(bank 1)
536=Brake On/Off (BOO) circuit failure/not activated during KOER
632=Transmission Control Switch circuit did not change status during KOER

The 536 code may occur if you didn't stab the brake pedal when instructed to during the Key On Engine Running test.

311 and 314 indicate that your smog pump is disconnected.

Is it possible that the vacuum line hooked to the EGR valve is leaking and not pulling enough to open the valve?

Ignore 536 and 632, you just didn't cycle the brake pedal nor the O/d switch when you were supposed to.

Have you disabled the smog system? Have you checked the tiny vacuum lines that hook up to them???

Thanks for the reply's.
For the smog pump questions: I have not deleted the smog pump; but I am going to check those vacuum lines, both smog pump, and the metal egr tube from the headers to the egr.

Thanks for the help.

I was messing with my PCV valve earlier, and I got codes 311 and 314 (im almost positive that is what caused it). I disconnected the pvc from vacuum and the light came on. Don't know if this helps, but I just thought I would throw it out there.
