Somewhat similar situation that I have with my 02 which began after I installed a Yoshi exhaust (no power commander). Runs strong with no pops and has been that way now for going on three years with average 35-40 mpg. My thoughts, which may or may not be correct, is that the loss of back pressure causes a rich idle due to the eci not being able to compensate at idle range rpm.
