For 96530706 Try the above explanation using tables "Post cranking Transient enrichment vs coolant temp #1 and #2 "
these add fuel after cranking and decay over a few seconds per mrfred's explanation. I think you want to add time so that it continues to add fuel.
change the values in table # 1 for 45- 122 degree temp so that they are 120 or more tapering down ie 45= 120 etc 68=100 93= 80 122= 60. Leave the rest alone. Test and see if that helps.
If not then do the same for Table # 2
Test and see if it helps

Spent 4 hours in the car just fix that idle. The Idle wont go past 1000 rpm what ever steps i use , upon load with a.c and lights on it drops to 800 - 750. AFRs are like see saw, back n forth. Give some throttle and it goes lean and then back rich. As soon as i take rpm to 1300 every thing gets better.

Sorry for the revival of this old thread but does anyone know if the Post-Cranking IPW adder #1 and #2 tables can help richen AFR after the car has been started?
I have noticed that whenever my car is started when warm (operating temps) the AFRs are a little lean (high 15's to 17ish) for a few seconds. So i wonder if i were to increase the ms in the desired temp ranges if it would help richen it? Since they are 2 tables is one for the main maps and the other for alternate maps?
Thanks in advance
