maybe its related to A/C compressor which obviously takes some power
from the engine.
mine 4.6 does the same, its normal i guess. Without A/C it idles
fine, i have new ignition wires, new spark plugs and MAF cleaned,
and air filter new too.
Dont know what else could affect the idle speed, its controlled
electronically, no any adjustments,

I've got a 1997 Lincoln Town Car, Cartier Series.
I notice that when idling in the Drive Gear, the car sometimes
surges ahead, occasionally with force a bit stronger than
the force with which I've got the brakes holding it back.
And sometimes, the engine dips really low, almost to the
point where it seems like it's going to stall, which
thankfully it doesn't.

One other pattern: the car only does this when I've got
the heater or A/C on.

What could this be and how might I repair it? I took it to
Midas and they adjusted the idle, which helped but didn't
ultimately solve the problem.
TIA.
