Everbody would be just shooting in the dark about this so I would suggest if you don't have an OBII system tester or AutoTap you take it to someplace like AutoZone and have them test it for free. In the mean time you could look for loose wires/wires touching the headers, vacum leaks. Good luck and let us know what you find out.

.thank guy for any help.could take a volt meter and at the conector of the harness from the the car
put the meter leads on the two brown wires, should be C and D pins i think.
and turn the ign. on, and masure the voltage, should be about 12 volts
if less than 11 volts check the ext. wires or the sensor fuse.
if there is about 12 volts than it is the O2 sensors.
hope that helps.
