CHECK ENGINE Light on
I just installed a new muffler on my 94 Cherokee and when it gets up to running temp the check engine light comes on. Has anyone else had this problem or know why it is happening?

Go to Advance Auto Parts and have them hook up their programmer to tell you why your check engine light is on in the first place. They will do it for free and can either tell you whats wrong or will give you what code it is.

Remove both bat cables and hold them together for 10 seconds. That erases everything. After reconnecting cables take it for a good drive, at least 20 miles, so that it can relearn the parameters.
