Thanks jfpilla.
Those figures were derived using the RAFIG/RAFPN process.
Could they still be wrong?

YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T
MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE
DUCT TAPE.
IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

It's worth trying. Desired airflow is important. Often when it's very correct other tables stay stock.
I prefer logging IACDES_B (IAC AIRFLOW) and using MAP B4307 A/C off RAFPN.
Start with the stock table and make the same additions or subtractions to both columns. Log from startup and idle to at least 92*C. I've never not had to finish by SOP.

Hmmm...still bucking!
Still looking.
How am I ending up with numbers as low as 10 or less AFR?

I logged IACDES_B and when using MAP B4307 A/C off RAFPN, these are the numbers I get.
-0.378317
-0.833999
-0.651416
-0.757419
-0.829980
-0.830892
I'm still getting the same bucking.
Here I marked it right as it was bucking at frames 7565 and 7571 ???? I don't see anything.

And here's another log...I changed the PE delay from 1 to 0 as per one dc_Justin's suggestion in another thread in order to get rid of the lean spike as I touch the accelerator whilst cruising.
I got some bucking at frame 7131....there's 3 markers next to eachother. I was hitting '1' as it was bucking.

Hi All,
thought I ought to post an update.
Found the cause of bucking...or so it seems.
I had a heater hose running against the ign module/coil.
Moved the heater hose away and no difference.
Swapped coils and it seems to be fixed.
No bucking in 3 days....and I tried to force the Burb to do so.
