I replaced the coolant temperature sensor and the truck immediately started right up and ran much better. No hesitation anymore, didn't have to pump the gas to get it started. It also drives and shifts better now. It still seems like it's running a bit rich, but maybe it's just my imagination. The exhaust smells a bit rich, and even on a warm day, like today, there will be grey smoke coming out the exhaust until the truck warms up. Thank you for the advice on the CTS.
