I got my engine reassembled today. While I had the motor a part, I tighten the tension inside of AFM because the A/F was going down to 10:1 @ WOT. (that was on 4th gear pull on a dyno with W/B)
Now, when I get out of throttle, the A/F (narrowband inside of car) voltage goes down to 0 volt:shock: (well, the voltage flickers, 0-.7v backand worth)and stalls. I was trying to see if there are cures out there without having to loosen the AFM. The A/F is fine WOT now, (11.5 on narrowband, with 1370deg F EGT) Any idea? Thanks
