Default Erratic Idle & Stalling....PLEASE HELP
2001 Silverado 4.8
After I installed my new Yank power adder torque converter I have erratic idle & stalling issues at idle or during turning. Can anyone help or point me in the right direction, I feel it maybe tune related but not sure. I have a On3 70mm kit with walbro 450 fuel pump & 60# deatschwerks injectors, tuned speed density by Fonse Performance.

Obvious places to look are pinched wires and vacuum leaks.

What’s the size of converter? What’s your idle speed in park and in gear? Does this have a decent cam?

In regards to both -

When I did my stall and a buddy’s - the idle airflow desired and the idle learn had to be adjusted

must’ve been due to it being able to spin up faster and come down faster - just something to look at- I’ll post a pic of what I adjusted my buddy’s to
