On the closed loop parameter a/f ratio table, the bubble is now floating at 13.5, the target afr.
What do i do now? The TPS is straightened out. I think the TV cable was too tight.

Basically, I run the FAST in open loop at idle, usually. If your target is 13.5 and your actual is 10.9-11.2, that's because it is not correcting to 13.5, it's in open loop until 1. the temp is a minimum of 120* and 2. the RPM hits whatever the closed loop setting is at. I usually set closed loop to 1250-1500. Basically oof idle.. Idle a/f is usually around 11.5 to 12.0 in park or neutral. When you put it in gear it will usually lean out to 13.0-13.5. If the idle is smooth, you should be fine, if not, it may be too lean and you have to play with the numbers in the VE table to get the A/F that works best.. make sense?
