The thermo-time switch is just that: Runs the CSV ONLY for X amount of seconds at Y° (I have a chart at home somewhere). It will NOT inject when the car is above 50F I believe (maybe cooler) and it will NOT inject for more than 2 minutes at any temp. The CSV and thermo-time switch can easily be ruled out.

Your problems are probably not related. D-Jet, when finicky, can be a pain to diagnose and you may think things related. I would look at your aux air valve. Make sure your throttle plate and linkage are adjusted correctly or you WILL have all types of issues!
