my silvia (CA18) has a tough time idlling when it first starts up… it has a miss fire all the time, and im pretty sure that its a really dirty injector, but i dont know why it wont idle in at start up, after i drive it for a minute it idles fine… so i think in closed loop something is sending a faulty signal… ie, hO2S, or idle control valve not working… so if anyone has any info, let me know b4 i go dig in on it…
go to cnd tire and buy a bottle of there motomaster injector cleaner. Its pink and in a cool bottle that will meaure it for you. Works great for the idle.
yes evan! i would recomend that i had very oily injectors from when turbo was blown injector cleaner took it right out!
haha, yeah, i tried the easy steps already!
