Default IAC Valve problems

Hey guys, I've been having a problem with mine. I pulled the codes but didn't get anything. I ordered the IAC valve because I can't find anything else wrong with it. I got in online from Autozone for ONLY 55 Dollars!!!!!!! I'll let you know if it fixes the problem.

Usually when there is a problem with the IAC, the SES light will come on, and give you a code...(I don't remember the numbers) but you should actually get 2 codes. Left and Right bank too lean. </P>


Something like that. $55 is like a sore dick. You can't beat it. Might as well replace it.</P>


</P>

Yes...You'll just get 3 or 4 different codes, but they'll still be in there.</P>

yeah i know i need to get mil eliminators i put the new iac valve on yesterday and the car will idle now but it has a real bad lope like i have a cam or something and the rpms will hang for 3 or 4 seconds. i can still hear air sucking from somewhere. is it possible that the seal in between the throttle body and the intake is bad. that is the only thing we can figure out
