I am having difficulty starting my Nissan 310. It is ticking over in an uneven manner. What could be the possible reason, and how can I mend it?
If you can't start your engine that easy or you have noticed that it is idling unevenly, the usual problem is with your AAC (Auxiliary Air Control) valve. When your AAC valve is dirty or faulty, you will really have problems starting your wheels. Basically, it is caused by your ordinary use of your wheels over the years. Carbon deposits rise from the engine and cause it to work in less than ideal condition. To solve this minor problem, you will need to remove the AAC and clean it out. This should cure the problem. Just a reminder, cleaning your AAC valve is not an easy thing to do especially if it would be your first time. You will need assistance from one having previous experience.
One of my headlights is not working properly. It is not operating as it should. How do I fix it?
Disassemble it, remove the turn signal lever, and clean the contacts. This will solve your problem about your headlights malfunctioning. If after doing this procedure, you will still encounter the same problem, I think you need to get a replacement. However, you need not to get a brand new headlight. Getting a whole new one will cost you a lot of penny. You only need to inspect it and change part/s you will find not functioning well such as, cable, bulb, igniter, ballast, etc. Get help with this one from an expert. You could set off the airbag and hurt yourself or damage the vehicle.
I have a Nissan 310, and I am having trouble every time I turn over. My engine drags or hesitates when idle or under load. What could be causing this?
Those are symptoms of a malfunctioning Mass Airflow Sensor (MAF Sensor). It could be that your MAF Sensor is in bad condition, which leads to low compression, low vacuum, or low fuel pressure due to a bad fuel pump. That is a very common encountered problem from ordinary wear. The MAF Sensor could get contaminated or damaged. This often happens when the air filter is improperly installed. That allows unfiltered air into the engine. As a consequence, the MAF Sensor cannot measure the amount of airflow accurately. This can cause various drivability problems.
A dirty engine as a result of carbon deposits also causes poor performance of your vehicle. You may resort to either carbon cleaning your engine or replacing it. The first option saves you on costly parts. So before going to the mechanic to replace it, try to carbon clean it first.
Just a tip to prevent this problem and prolong your MAF Sensor's lifespan and performance: Do not wait for your MAF Sensor to fail before cleaning it. Clean it every six months, every time you change oil, or every time you clean or change your air filter.
