Let this wash over your brain for a moment: 1994 was 20 years ago. Next year, people will be old enough to walk into a liquor store who weren't alive when Snoop Dogg brought us Gin and Juice. There are people right now old enough to vote who were toddlers when OJ made the white Ford Bronco famous. Now Ford finds itself exactly two decades removed from OBD-I programming codes and blinky light diagnostics; and if you're too young for that to make you feel old, you'll get yours in 2024.
The 1994 model year was the last for universal OBD-I programming at Ford, before 1995 brought a shift to OBD-II. Code 332 is a common one on vehicles of a certain age; it translates as "EGR did not open/respond during test or if memory code, did not open intermittantly - EVR or PFE." In short, that means the "Differential Pressure Feedback EGR" sensor on top of the EGR valve either isn't working, or isn't reading enough vacuum from the intake manifold. The DPFE sensor compares the pressure from the intake to the pressure in the exhaust, which tells the EGR valve how much to open. A DPFE malfunction will cause the EGR to act up or fail, often causing a loss of power or fuel economy. On vehicles this old, it's not uncommon for the sensing passages in the EGR assembly or the assembly itself to clog up with soot and carbon, causing a low vacuum signal to the sensor. Try removing and cleaning the EGR assembly, and cleaning the carbon out of the passages in the manifold. If that doesn't work, the sensor is most likely bad.
