idle air control valve
 

well i put my new intake manifold and throttle body on the other day so i started the car up it ran fine then like 2 seconds later while its warming up the idle jumps like 500rpms from 1700 to 2200rpms and it pops a cel but the car runs fine it doesnt stall out or anything it runs fine just has a high idle once the cel goes off other then that it will idle at 750 when fully warm untill the cel goes off. anyone else had this problem i think i might have a fucked up IAC valve

code 14 is the worst code on the planet :-\
sounds easy to fix but sometimes the ecu takes a crap

no i havent had a chance to even check the codes yet i been really busy lately with work and ---- but i was woundering if anyone else had this problem but i do have another iac valve in my garage waiting to be put in if it is bad and this one works its off a working motor or what was a working motor im gunna fix it tomorrow or see what it is atleast and yes the do suck specially since i just put on my skunk 2 manifold and it sits about 1/2 inch away from the firewall and no my ecu is good still i just upgraded to uberdata

Set the idle as per the owners manual.

no its really weird my idle is fine becasue after driving around and ---- when i start my car it will idle at 750rpm then jump to about 1500 i think it might be a problem with the new throttle body but im gunna change the iac to see if i can get rid of the cel
