1991 Dodge Shadow 4 cyl Front Wheel Drive Automatic
2.5 (non-turbo) engine idles at 2000 rpm and drops to about 1500 when placed in gear. Codes 12, 13, 14.
I know the battery disconnect caused the code 12
According to the information I have, the codes 13 and 14 refer to the MAP sensor.
I replaced the MAP sensor (twice) with used sensors and checked the the vac. Lines from the throttle body to the sensor. I located a ground wire that had broken from the O2 sensor plug to the engine block. Repairing this made no difference. I also unplugged the MAP while the car was running and it did not change the car's idle.
have the same problem?
