It depends on where your sensors are in your headers. Mine are down in the collector and they could cool off with excessive idling. This would cause it to run really rich until the computer would realize it and drop out of closed loop. New heated sensors took care of the problem. I used the fuel pump enable wire from the ECM to trigger a relay to power them. I like this because it is only on when the engine is running therefore the sensors aren't being heated in just the ON or ACC position. It will make a big difference in the ability to tune it accurately. |
