What causes the Mitsubishi Pajero V73 to stall when braking due to low idle speed?
1 Answers
There are many reasons why the Pajero may stall easily at idle, such as air intake system leaks, excessive carbon buildup in the throttle body, low fuel pressure, clogged air filter, fuel injector spray pattern issues or leaks, improper idle adjustment, faulty spark plugs, or malfunctioning mass airflow sensor. Idle port clogging: When experiencing unstable engine idle, first adjust the idle speed. If the issue persists after adjustment, check whether the idle jet and idle air jet are clogged. If clogged, clean with gasoline or acetone and blow through with compressed air. Intake system leaks: If the jets are not clogged, stabilize the engine at a constant RPM and listen for leaks at the intake manifold or carburetor gasket areas. If leaks are detected, resolve by tightening screws or adjusting gasket thickness.
