aight i have a 91 teg ls b18a1 i just replaced the clutch and tranny i havent ran the car hardley since i lost my lisence in january and its just developed somthing wierd with the way it revs it idles kinda rough but the problem is when i go to rev it up if i rev it fast its fine and fairly smooth but if i slowly rev it its like i have a launch control or just a wierd skip but it dosent stop from going up in the rpms it does it from 1,000 rpms to like 3,000 after that it seems ok i looked at the ecu flashing code and its 1 long blink with 4 fast blinks code 14 i looked it up and it says its the IDLE AIR CONTROL VALVE but ive been told that the IACV should just be for controling the idle but the person that told me that is kind of a moron but i was wondering has anyone ever heard of one doing this or had this problem??? and did the IACV fix it?
