so when i come to a stop light my idle drops real low and when i go to take off it sputters until i get in a little higher rpms i put a new iacv on not to long ago and it still does it

my car is a 91 hatch and i put a d16z6 i rewire the car over to multi port and im useing a 89 si dizzy and si computer and i have know clue what it is im not geting any codes at all other then the o2 sencor once in a while

 

try adjusting the screw on the tb that controls idle

 

I don't recommend screwing with the idle screw unless I would know it was the cause.

Does this happen under all weather conditions? The o2 sensor could be the issue, cause it might not throw a code, its just getting less accurate.

 

i put a new oem o2 in not to long ago i had new vavle silse in my head it might be the prob i did a compression test and im 180 all the way across i have new piston ring to put in but im debating on just geting a new head

 

check ur vacuum hose that connects to the pvc valve on the mani

 

also check your timing the mini me i just built was doing this crap it was one tooth retarded by the cam gear moved it forward a tooth and bingo

 

i hate doing time becase every time i do it it it moves on me when i try to put the belt on the came gear so if there s a better way to do it ill do it that way
