The rubber boot connecting the throttle body to the intake
manifold tends to crack. This can cause hard starting, rough or erratic
idle, and engine performance problems.

Came on slowly, until could not hold an idle at stop lights. Sound from under air cleaner is a loud whooshing sound like a vacuum cleaner. Also, I sprayed carb cleaner at the boot and the vehicle accelerated.
