    how lean is too lean for idle?

    I have been having issues getting my idle right. If I get it to idle around 14.7 it will for some reason go rich every few minutes of idle and then slowly lean back out. I hate this sitting in traffic and watching it all of a sudden idle around 11.0 and then lean out. Anyway I played with the tables a little and now it idles in drive between 15 and about 16 and never seems to go very rich. When it is in park some times it will go leaner into the 16's but bounce around into the 15's warm. It idles fine and the EGT's around 1000 degrees. Is this too lean? The only issue I have is when starting not always but sometimes when starting cold it will start right up but idle fast near 2k. If I turn the key off and restart it immediately it will start and idle normal. I am thinking mabe one of the tables is too lean causing the start to idle faster. My FWD cal was idiling about the same but I was not sure if this is too lean.

    Thanks

    Yep. I can get video. Sensor is good to. The smoothest I've seen it idle at a given af is 16.0. I wouldn't be worried about running lean at idle unless it just doesn't wanna run.

    Mine stays pretty stable at 14.7 ish, used the LC1 and would idle at 16-17:1 but started acting up last night. Didn't really find any MPG gains using it over the cal using the ox sensor.
