After changing my plugs on my 2004 Chavy Colorado, I have a slow idle engine light. I replaced the MAP sensor-no change. Any idea on any other sensor to replace? I also have a lean mixture code with the slow idle. All I did to cause this is change the plugs.

check all the connectors\vacuum hoses near the area that you worked.....one might have accidentally been unplugged or partially unplugged.....if you can get the engine light checked out that'll probably tell you exactly what sensor to look at
