ENGINE MISS

1988 Nissan Truck

Engine Mechanical problem
1988 Nissan Truck 4 cyl Two Wheel Drive Manual 160000 miles

Persistent engine miss on one cylinder is cured for a short time by fitting new plugs, points, etc. Returns within 500 kms. Engine has been overhauled - piston rings, bearings, etc.

Engine running rough or misfiring can be cause by the following: 1. Defective spark plug
2. Inadequate spark/coil, defective spark plug wire.
3. Lack of compression
4. False air leakage.
5. Faulty fuel injectors.
6. Insufficient fuel pressure.
7. Contaminated fuel.
8. EGR valve that is leaking.
9. Oxygen sensors.
10. Throttle position sensor.
