yj running rich

I have a 95 yj I recently swapedd on the 4.0 throttle body onto my 2.5. I bored out the intake man. To match the increased diamater. Now after hard acceleration I get a really strong odor smell. Which leads me to believe oit's running RIch? Any ideas? I swear this thing is getting 9 MPG with 33's and 6 inch lift.
