Did a quick search and didn't find anything so I thought I would share. The Fitech CTS reads low, by about 20 degrees, this will affect your EFI maps and cause enrichment. My car showed a maximum of 168 degrees, I changed out my thermostat, this did nothing. I read the Fitech CTS sensor often reads low. I changed it to an AC Delco 213-928 and viola it reads 186. I also put in a set of hotter plugs, the combination of the two really made the car run better. If you are certain the EFI temperature is reading low, spend the 20 bucks and change out the CTS to the AC Delco unit.
