Engine Stalls

Engine starts but dies after brief idle. Engine runs only if accelerator is held at part throttle. Engine dies as soon as any load is placed on engine (turning on A/C or engaging transmission). If any of the above conditions applies, check the following items:

• Ensure air intake system is unrestricted.
• Check PCV system.
• Check ISC valve for malfunction (Tracker).
• Check coolant temperature sensor operation.
• Ensure engine is not overheating.
• Ensure fuel system pressure is correct. Use ohmmeter to verify correct fuel injector resistance.
• Check EGR system for correct operation.
• Check for cracks or poor connections at throttle body.
• Verify correct throttle position sensor adjustment and resistance value.
• Disconnect MAF or MAP sensor. If condition is corrected, replace sensor.
