i will start by saying my set up which is a b16a2 with inline pro dual valve springs, ajustable cam gears, intake,megan headers, integra injectors and tune on crome. now everybody knows my set up my problem is that every time i start the car on it starts sputering for about 3 to 4 mins and then it runs fine but the idle wont go lower than 1500 and it will go up and down from there till about 1700 rpm. I have try changing the injectors and nothing as well as cleaning the around the throtle body and cheking the spark plugs and nothing. I also chane the IAC. CAN SOBODY PLEASE HELP!!!!!!

 

does this happen when the engine is cold or warm, or both? does your intake manifold have a fitv?

 

it happends both when is cold and hot and the intake mani doesnt have a fitv

 

i also just found out that it didnt have the check engine light on so i put one and now that is coming on. i try to do the jumper wire due to that it has been converted to OBD1 but is not flashing for some odd reason
