'95 850 Turbo Drops RPMs Randomly
My '95 850 Turbo randomly drops about 500 rpms when driving. Could be in city or highway. Driving me crazy. It does not do it when idling. Mechanic says no codes popping. He has adjusted the Idle Control Screw several times. Says could need and Idle Control Plate. Any ideas what might be causing this problem?

Thanks for the suggestions. You are right on the Throttle Control Plate. (I am a new Volvo owner so I am still learning all the terminology).
The misfire makes sense, but wouldn't that cause a "code" to show up? There are no "codes" showing up.
Could it be a problem related to a vacuum hose or the fuel pump?
The O2 sensor also makes sense, but again, wouldn't a code show up for that?
