block learn still at 90
I have changed to a heated o2, reset the idle to aprox 20 setps at idle in drive. I still have the problem with the blm going to 90, it will go to 128 but then falls back down. I had AFI reburn the prom, they said if it still don't work you have another problem.

IMO, it is never going to run right until you DIY Tune it.
