how to richen up a/f

[whosyourdaddy?]

My jeep is running lean and Im not sure how to adjust the mixture? I though there would be some way to adjust the air flow meter to richen it up. Any suggestions.

What year and what engine? And how do you know it's running lean?

Dad, I am going to try this myself.......

MAP sensor Modifications so you can adjust fuel/air mixture (http://www.madxj.com/MADXJ/technical/technicalfiles/BAadjustableMapSensor/AdjustableMapSensor.htm)

That actually sounds not to hard. I've had other cars that you could drill out a hole in the map sensor and then adjust it with a tiny screwdriver. Anyone done this? I did it on my wifes Toyota Cressida to get it to pass e-check.

Dude,

How do you know your XJ is running lean? Also if i look at your profile you list a 2001 XJ so you should have some warranty. Before you start messing with stuff have the engine controls hooked up to a test set and see what wrong.
