1992 Mercury Topaz - 1992 Mercury Topaz

I had the same problem. It was the idle air control valve. It sits on top of the intake just downstream from the throttle. There's a valve rod inside that gets worn over time and starts to stick. If that's what is causing your problem, you need to replace the unit.

SOURCE: Where is the fuel pump relay located on a 1992 Mercury topaz

the fuel pump relay is located on the left shock tower in the engine compartment in a black box 6x4x1 inches. there are other relays inside the same box which is actually called the ccrm or constant contorl relay module, there should be a double connector with 20 to 26 wires in it, hard to miss.
