some times when i come to a stop and push the clutch in i notice the rpm's going up 900...1000...1100....1200 and stop around 1200 and my a/f gauge goes to full rich. and when you step on the gas it kind off tries to stall or like its fulded. than as fast as the problem happens it just stops and the rpm drop to normal and the car runs fine
all i checked and replaced was the IAC sensor

Mine does the exact same thing, except for the almost stalling thing. I think that it might be normal for the idle to stay up a little high before you come to a stop. Maybe try an idle relearn and see if that fixes the almost stalling part.
