Start up airflow.

Unread postby Thicklovin » Thu Jan 25, 2018 6:38 pm

I'm having this issue when I crank the vehicle and I have to feather the throttle to get it idling correct. Sometimes when I re crank it. It will follow the idle air table and rev up then come down. When it does this I have no problem idling and throwing it into gear and it not stalling. When it doesn't follow the table it will die when I throw it into gear. Basically when I crank it the first time and after I cut it off multiple times. It will not rev up like it's supposed to. Mechanical idle problem? Tune?

Any ideas?

it should be obvious at startup, make sure ipsibr and dashpot isnt ramping up

it kinda sounds like you need to kick up the crank iscdc function to open the iac more during crank

do you have the throttle stop set correctly?

I think I may have fixed it. Does it more at cold temps. I ended up redoing idle and making some adjustments. The crank isdc function is maxed at 99 in my tune.
