1995 Saturn SL Q&A

1995 Saturn SL Question: Temperature gauge doesn't work since I changed the coolant temperature sensor.

Car would idle rough when cold. Changed PCV and MAP, then put in coolant temp sensor. Car runs fine, but temp gauge doesn't work now. Took off and turned 180* and sprayed with carb cleaner thinking it may have a coat of anti freeze on it. Do I need a bigger hammer? Thanks for the advice! -
