Hi Terry, Listee Kay Fremgen had your exact problem he had changed every thing. He dropped by for a few days and we started swapping every thing again. It was a bad afm (air flow meter). He had swapped it before but some other problem developed and he had never given the new afm a thorough test. His would fail in closed loop only. If he pulled the o2 sensor wire to the ecu and forced open loop it ran fine. Like you it only failed just off idle. It had a cracked circuit board wiper surface inside the afm. Darrell Ps. Kay and his friend Valeria are traveling in South America at the present time.
