switching to 3.8l coils $8B

I'll have to drive it a bit more to see if the idle stays down. seems like i have to drive this thing for a week or 2 before it learns the change or does whatever it does not to do odd things. I put the timing back where it was to begin with, it got worse gas milage and was kinda slugish, after that ve was pretty lean but it got colder outside so i adjusted that, will c what happens.... I have the worse time with outside temp change. I got u on the Definition. I downloaded at least 2 different or what i thought were different $8B XDF's When I have more time I'll look.

Hiya,
I don't know if it matters in this mask. I have always found most GM stuff requires the tps voltage to be between .5-.6v for idle control to work correctly. Most times with big cams that need the extra throttle, I just drill the blade. Then as you know, it won't want to decel correctly so I kill a shit ton of timing in the decel areas to help with that.

I was watching the % on it so dont know what the voltage was. I had to close the throttle on it. May try that on my truck though
