Your mixture is calculated based on the input from various sensors. If you just put a new engine in, it's possible one of the sensors wasn't reconnected or not snug. You should check for error codes as this will help you find the problem. If you check the FAQ section (near the bottom) there's a how-to (you don't need a scanner) and list of error codes. Happy troubleshooting!
