Where is the distributor cap located on a 1992 Plymouth Voyager?
The distributor cap is located where the spark plugs cables are connected .They go from the motor to the distributor cap.
What could cause a 1992 Plymouth Voyager with 190000 miles and a rebuilt transmission to stall when put in gear?
I've had my '97 Plymouth Voyager stall going into gear (from park) when the transmission fluid was really low (down more than a quart). I've also had that same van stall when an O-ring in the distributer got bungled up, presumably from spraying the engine with a pressurized hose. Oops :) The distributor problem was very hard to diagnose.
Try eBay! Just search for "1992 Plymouth Voyager manual", and check the listings for one that includes the Infinity supplement. If the radio is an OE radio, then the information is listed in the owner's manual. Don't have one, get one. Contact your dealer or a salvage yard. If it is a non OE radio, contact Infinity. Mine (a 91) has a separate sound system manual.
