1991 Mazda Navajo ProblemsEngine Stalls when Coming to a Stop, Rough Idle
If the engine stalls when coming to a stop and/or has a rough idle, it may be due to sludge accumulation in the throttle body and idle air control valve. The throttle body and idle air control valve will need to be cleaned if there is buildup.
If the engine cranks but does not start, it may be caused by a tripped inertia switch. Switch the key to "ON" and the fuel pump should be heard running for a second or two. Listen at the gas filler if necessary. The inertia switch is located on the firewall and can be tripped when the parking brake is set too hard and then released. The inertia switch should be reset, and will click when it is reset.
If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.
