Ah i seeeeee.......looking at it from a mathematical side......theres about 84 ohms per degree, so being 100 ohms out to the ECU will only be +/- a degree in tmeperature or so anyway, and being that far up the temperature range i cant see it being a massive issue.

Usually its cold starting issues that arise from the the CTS i believe (although i could be wrong), i'd try that map sensor if you can find time in your busy schedule to undo 3 screws
