When at idle the car is fine. When I Shift into gear feel like it's going to stall but doesn't. Drives fine but when I press the brake to slow down it stalls. Turn the key starts back up perfectly fine. What can the issue be?
 
What are your IAC counts on the scanmaster?
I fixed the stalling issue. Today I got it up to 75mph but when it got there I sound like the rpms was to high. Like if it was an high idle while doing 75?
