Doubtful, I'd start with cleaning the throttle housing.

Sounds simpler than what I was considering.

Try replacing the pressurized gas cap. Get the correct one - mine said
"pre-vented." Made my 92 SE stop all that rough running immediately. See my

The first part of my search was the supply side of the fuel system:
1. gas cap
2. fuel filter replaced
3. pressure and flow tested the fuel pump
4. replaced the fuel pump relay, which led to replacing the alternator -
intermittent, thermally sensitive voltage regulator, insufficient voltage
at low RPM, excessive voltage (16 to 18 volts) at normal highway RPM. Only
thing symptom was that occasionally the ignition lights would stay lit.

And now, as per Steve's suggestion I'm checking out the throttle chamber.
No detectable play on the main valve stem bearings. No obvious cracks in
vacuum lines, however inspecting the bottom of the air-flow meter to
throttle plenum requires a skinnier forearm than mine to hold the QX3.
Only thing that looked not normal was the wet smudge on the manifold at
the base of the fuel pressure regulator. Could that be my problem??
