There is no idle screw. The idle control solonoid is on the throtle body and sometimes it can get dirty needing cleaning. ---- Well, this is assuming you have TBI or fuel injection, or if it is a carbuerated engine, if it is FI, the idle is set at the factory, no adjustment to the idle is recommended, as the computer controls the idle in FI engine's, if you must, their is a idle adjustment screw under a tin cap seated in your throttle body, an awl or a similar tool can remove this cap, is it located directly in front of the throttle stop, lower right of your TBI unit. jr Since in 1992 there WASN"T a carbureated engine in that car, if you are having idle problems the culprit would be the Idle Air Control Valve (IAC Valve). There is no cleaning it, only replacing it will fix your issue, assuming you don't have an intake gasket leak. Scott
