Nissan 1400 how to replace front wheel bearing for Bakkie 1400

Replace EGR valve

Have you checked for any vacuum leaks ? Have you done a complete and proper tune up ? Any codes in ECM or an engine light on ?

In general there are fewer ways to adjust the newer carbs than the vintage carbs of the past. Often the vacuum at low idle is the problem and you should check a vacuum port on the intake with a Vacuum gauge. Sometimes an EGR valve does not shut completely and the engine struggles at idle. If you find that vacuum is adequate, you can adjust the air mixture screws to provide the highest vacuum reading and then crank them in until the vacuum falls less than 1 inch. It might be beneficial to run the engine and spray a water mist from a hand powered spray bottle around the seams of the intake and carburetor. Also spray any vacuum solenoids or lines. You will notice a change in RPM if there is a leak. You may have a fuelpump problem A clogged fuel filter or low pressure can affect how the car idles. Please rate my info.

If your check engine light is on have it scanned for fault codes. Also check to make sure you don't have a vacuum leak, you could of pulled a hose loose accidently when you changed your plugs.
Signals from the oxygen sensor, and/or a bad throttle position will also cause engine surge.
Good luck, i hope this helps.

Check operation of the PCV valve and condition of associated vacuum and vent hoses.
Check also for any air leak on the air intake system.
