Quick question (I think my SC might have a vacuum leak).
When you guys turn on your A/C, do your SC's lose vacuum?
My car is acting up. After it warms up, when it's idling (like at a red light or stop sign), once in a while the RPM's will drop to about 400 and the car will stumble a little bit. After a second or two, though, it will return to normal. Also, when I turn on the A/C, sometimes it will do the same thing (drop RPM's and feel like it wants to stall). Again, after a few seconds (or if I jab the accelerator), the car will return to normal. The weird thing is that with the A/C running, I only get about 13 inches of Mercury of vacuum at idle.
Other than that, the car runs OK. I get 19 in. Hg of vacuum at idle (with A/C off, of course), and about 12 psi's of boost at WOT.
Plugs (Motorcraft double plat's) and wires (Magnecores) are about 6 months old.
Other people have also suggested an Idle Air Control Valve on its last leg. Any opinions?? Thanks.
