my car seem to be running rich at idle. is that normal. when i first started the car it was lean until the computer relearn itself and now its rich. what should the a/f be at idle.

also when i rev the car up ( no tach so i dunno the rpm ) just enough to hear the greddy rs bov, the car starts to bog sometime shut down as the rpm drop. the car jumps to lean. any suggestion. this is a blacktop s13 with a fmic and 255 fuel pump and 300zx fuel filter.

If you're running a vented BOV, then it's normal for the car to bog after shifting. All of the air is leaving the system, but the MAF doesn't register the air leaving, so therefore too much fuel is dumped in and you'll run rich.
