From what I found this date was about the time the changeover from EEC IV to EEC V (PCM'S) and the dual throttles were changed from vacuum operated (my car) to electricaly operated. This might only apply to the UK. 
Um, this is a load of misinformation.
The only Contour's with EEC-IV PCM's are 1995's. 1996+ have EEC-V. The IMRC valves went from vacuum to electrical at that time, also. Has NOTHING to do with throttles.
