I know this sounds lame, but my 1994 manual states to depress the go pedal in park or neutral per trans type, and rev for 2 minutes at 2000 rpm, as a remedy to clean up dirty 02 sensors...now..why a blast down the highway at 2800 rpm does not do the same thing..is beyond me, but I know if the 02's are not working right, a host of settings in the control module are effected, air/fuel ratio, etc. so probably time for either a wiring check, to the sensors, or worst case change em out, and its not a fun job, without a lift, and proper tools, heat, and something to hold your exhaust up as you try to remove the passenger side, I have fairly large hands, you will probably have to drop it down anyway, to get swing clearance to apply any leverage. Make sure you
re-coat the new ones with recommended never-seize.
Best to you, Derek
