my van will lose all power. gas to floor makes motor starts poppin. idle at
500 rpm. van doesnt really move. i just put in new temp sensor and o2 sensor.
only way i can drive it normal is keeping the o2 sensor disconneted. runs
perfect  with it unhooked. tried 3 different o2 sensors has soon as it goes
to closed loop no power. any ideas
