Question about Clarion DXZ838RMP CD Player
A common issue for this car,and usually an easy fix.usually its a result from carbon buildup on the tip of the idle adj. screw.in a simple explanation the pgmfi system is set to measure the amount of air flow passed the conned shape port of the throttle body,with carbon build up it gets false readings and is constantly trying to search for the correct adj. The reapair is to remove the screw clean the carbon off the screw tip and also inside the port where it is removed from with pressurized carb cleaner or brake cleaner bought at any auto parts store. The screw sits in upper portion of throttle body assy.,just above where air intake hose from air filter attaches.Its a large flat head screw,inset about an 1/8 of an inch.from the factory it comes with a protective film over so to make removale easier spray carb cleaner over screw and scrap away thin layer of protective coating.Then firmly unscrew idle screw all the way out,once removed you 'll notice the black sooty buildup on the end of screw.clean well with carb clean until all deposits are gone.Then spray carb clean into port of throttle body(where screw goes)wait about 30 sec or so spray again into port. re insert screw and screw in till it completely seats, then back out 1 1/2 turns.start car and hold at higher rpm to blow out deposits loosened in throttle body(30 sec or so)then let idle.surging should have gone away at this point. good luck!
