Here's the problem i'm faced with, my supra, even when warm has a very choppy idle, none of the cylinders are missing and compression is good across the board, coupled with the poor mileage i'm getting ( 45 miles on 3rd of a tank, screams vacuum leak, or something witth the AFM/O2 sensor, i've already gone over every bit of vacuum hose on the car and replaced it all checking for leaks anywhere i could by spraying starting fluid. Since this happens at idle i don't think it's a boost leak, but i'd be glad for any input or common issues i should be looking for
