A different approach that worked for me. I used B12 Throttle Body Cleaner. I located the vacuum line that runs from the Brake Master Cylinder to the Intake and disconnected the line at the master cylinder. Ran engine at a fairly high rpm and kept feeding the B12 through the system. To finish things off I cleaned the Mass Flow Air Sensor (MAF) with MAF Aerosol Cleaner. My engine runs beautifully and is very responsive ever since.

Had the same issue on my 1996. Changed the O2 Sensor that is aft of the catalytic converter on the passenger side and that fixed it. Part was only around sixty dollars.
