Iat Sensor

Hello again! I got the EGR ports cleaned. Last time I posted, I thought I had cleaned them, but found a picture on the website that clearly showed me that I had not! Anyways, cleaned those and the MAF sensor. Reset my cptr with the neg batt cable off. After driving the truck for a while, the CEL came back on. I went to Advance Auto Parts to have the code read and it came back as PO113, IAT circuit high input. The po141, and 143 codes are gone, so cleaning the EGR ports must have worked. However, what does this new code represent? The truck still has a small amount of spark knock under load, and still smothers down under accelaration.
Thanks for the replies

Usually a P0113 after you've just worked on the truck means you forgot to plug in the connector to the IAT which is on the air intake hose from the air cleaner to the throttle body.
