ok so i did the headgasket on my car runs fine but now the car idles kinda funny when i clutch or cars in neutral itll jump up to around 2 grand then drop back down to normal idle didnt realy look at it yet but is this a common problem that has a easy fix off the top of my head im thinkin maybe the ditributor is clocked wrong of maybe the map sensor rubber seal might be loose but like i said didnt look at it

could be iac sensor

i also thought of that but i never had the problem before i ripped the head off so maybe i forgot to plug somthin in not a huge problem just kind of irritating

maybe a vacum line?
