Default Won't rev over 2500 rpm

I just ran my friends Genisys computer on her.Did get an odd code

IAT sens circuit high temp low Error code 23


Anyone know what this is?

She was running fine I went for a drive and had no power would not let rev go past 2500rpm

And once it warms up it sounds like it's going to come apart

Ok got the new IAT no change is there anyone who live in Saint augustine near or around the dobble red bus on us1 that could give me a hand?

Next question is there any way to test opti spark to see if thats the prob?

thats the little sensor in the lid....it tells the computer how hot or cold the air coming in is....this in turn tells the computer how much timing to add or take away in short....sensor is going bad....
