so my diagbostic as of right now, every 02 sensor i equip to the car, send a lean signal to the ecu and automatically the car starts running rich, even tho 02 sensor is showing lean, the engine does not know, my cel is flashing 21 when i pin te1 and e1.
ideas? someone help me, might have a vacum leak but ive replaced every vacum hose, whwn i connect the map sensor thru the air pipes (behind the engine) the car bogs ad doesnt drive, so i have a vacum hose straight from map sensor to the back of the throttle body, skipping the rear air pipes |
