Default RE: Replacing the A4LD Vacuum Modulator
I used to have a 93 mustang lx, and now I have one again. The old one would drop to idle when you released the accelerator, but this one doesn't.

Is that another symptom of a bad regulator, or is that a bigger problem?

The RPMS should slowly go down with the speed, acts like a brake sorta.

The only way to know if its blown is to take the vacuum line off it and see if transmission fluid comes streeming out
