driveability problem

[ksquare1]

As you drive vehicle it stall after acceleration when car is decelerating idle to low and then dies. Car starts immediately afterward already replace MAP Sensor no change. No check Engine Light On. Car has good power.

Sure sounds like a vacuum leak, or perhaps a leak in the air intake?

You don't state what year or engine you have, but a 96 I had, with a 3.0 engine, I had to replace what they listed as an Idle Motor for the same symptom as you , typically I would come up to a stop sign and it would die. It would start right up as long as I kept the RPMs up.
