Before swapping CTS you can check it with a DVM. Set DVM to measure ohms, disconnect harness connector from CTS, probe CTS terminals. At room temperature (22C) AC-Delco CTS should read about 2950 Ohms. At normal operating temperature (80C) CTS should read 338 Ohms. Cold engines require richer mixtures and your engine just needs to a richer fuel mixture than a stock calibration is delivering. This were ECM tuning comes into play - solving these pesky drivability issues as no two engines are alike.
