not too long, i drove around again today and the only code that showed up again was 35. I am going to clean the iac and report back

Cleared the codes and drove around for a while. CEL didnt come on, but still had the same problems. Ive had the car about 8 months and its been running great up until now. It has 170,000 on it

My suby is a 91 Legacy L Wagon and the past couple weeks its been having a lot of problems. Runs fine when first started/cold but when the engine gets to operating temp it starts having trouble and throwing codes. Problems are: Idles at 400 (idles at a normal 900ish when cold) Idle will randomly surge from 200-1000 over and over and will want to die Very sluggish under 3k rpm The codes thrown are: 11 crank angle sensor 22 Abnormal voltage produced in knock sensor monitor circuit 24 Air control valve inoperative (Abnormal signal produced in monitor circuit) 31 Abnormal voltage input entered from throttle sensor 32 Oxygen sensor inoperative 35 Solenoid valve inoperative Any idea what the problem could be? Possible fixes?
