i install 68mm tb and gsr cam onto my b16a, since then i having trouble of cold start. engine will not kick in high rpm to start and first crank take a long time to fire up, if i open a little on gas pedal it will start easier and also i have to hold the pedal and make it idle 2k to keep it running, if i let it idle itself it will die, and i know is alot do with idling at 700rpm on cold start is killing it. once engine warm up, no problem starting, and always idle smooth, once i hold the gas pedal for about 10sec to keep it running, the engine will start running(800rpm), but cold idle still won't kick in, until a min into running then it will kick in, (1500rpm)
i just wonder something i need to tune in the map? i don't think adding more fuel in cold cranking will do anything, i think i just not getting air, since if i open my tb then it'll start. i notice on the blox tb have no idle air adjustment screw like the stock one. anything do with that?
