okay I pulled 3 codes the other night all were KOEO. one was 63. this is the tps I fixed that and the code went away. another is 22, which I believe to be the MAP sensor. How can i check this? I'd hate to spend the money for a new one, anybody have this problem before. and lastly 81 thats the IAC right? I've already cleaned it out, but how should I test it to see if it's working properly. the car runs fine, I just want to get the cel off.
