After about 100 miles the light on again. Removed the TB and added some rv silicon and drove it about 100 minles and the light came on again. I am going to look for the leak in a different area.
JL,
The "check engine" light comes on for any number of reasons. Leaving the gas filler cap lose will also cause the check engine light. I know you just changed both filters and found lose carb in the process. Just don't limit your focus to the filter change.
Here's another good site to bookmark as well.....
