What causes my Infiniti M30's engine to misfire?
If the combustion process in the chamber is incomplete, the engine misfires. One common cause of engine misfires is a problem in the ignition. When the spark plugs, distributor rotor and cap, or ignition coils and cables wear out, these worn-out components lose their ability to transfer the needed spark to ignite the fuel/air mixture in the combustion chambers. An unbalanced fuel and air mixture, also known as a lean misfire, can also cause engine misfire. Worn-out mechanical parts, like the piston rings, cylinder walls, valves, camshaft, intake manifold gasket, head gasket, and rocker arms, can also cause engine misfires.
Whatever the cause is, engine misfires are dangerous as these can cause severe damage to the engine, so this problem needs to be fixed quickly.
What do I do if my Inifiniti M30 consumes too much engine oil?
As the vehicle gets older, it normally consumes more engine oil, however, still not excessively. Too much engine oil consumption can cause damage to the spark plugs, sensors, and the catalytic converter. Repair can get pricey especially if it already involves the catalytic converter, and not to mention the cost of replacing the engine oil every time it runs out.
The most common causes of too much consumption of engine oil are worn-out piston rings and valve guides. If the piston rings are worn out, your engine will experience low compression, while worn-out valve guides cause the engine to suck engine oil into the cylinders and may reach the parts that don't need engine oil. This problem can only be fixed if you replace the worn-out parts with new, properly-working ones.
There's too much vibration in my driveshaft when I'm trying to accelerate. What is wrong?
The vibrations can be caused by an unbalanced driveshaft. Just like your tires, driveshafts need weights to keep them balanced too. The weights are normally welded on the driveshaft. If the driveshaft is bent or dented, the mass is thrown off-center, which then causes the unusual vibrations. The driveshaft may also be already worn out, which can also cause the abnormal vibrations. Vibrations caused by an unbalanced driveshaft can be mistaken for a problem with the suspension, so for you to be sure, you should take your car to a service center.
Is it normal when I hear squealing sounds coming from my brakes?
No. It means that there's something wrong with your brakes. The most common causes of squealing brakes are dirty brake pads. Spray the brake pads with water to remove the dirt that has accumulated on them. If the squealing doesn't stop even after you have cleaned the brake pads, it means there's a bigger problem with the brakes. A meticulous check-up should be carried out to find out what is causing the squealing. You shouldn't take brake problems lightly since the brakes are very important for your safety on the road. You need to have your brakes repaired if there's something wrong with them, pronto!
Infiniti M30: Luxury to Fill the Gap
The M30 is the first vehicle released under Infiniti’s M nameplate. This mid-luxury, two-door GT coupe is basically a rebadged version of the Japan-released Nissan Leopard—a luxury sports car that was manufactured from 1980 to 1999. Below is a quick look at the changes and transformations of the Infiniti M30 during its short run.
An introduction to the M30
Internally known by its chassis code F31, the Infiniti M30 was introduced to the market in 1989 alongside the full-size luxury Infiniti Q45 model. The M30 was available in two body styles—a coupe and a convertible—both of which had two-doors. The M30 and Q45 models were released to fill a stopgap during a time when the Infiniti marque was still in the process of creating new vehicles to fill its lineup. The M30 was created based on the Nissan Leopard, but it still had several differences. For instance, since the M30 was released in the United States, it was transformed into a left-hand car to match its market. It was also equipped with several luxury features that were not present in the Leopard. And lastly, it was also equipped with a different engine, transmission, and suspension system.
Initial release in the market
Upon initial release, dealerships offered the M30 with a free cellular phone and CD player. It was also powered by Nissan’s 3.0L VG30E SOHC V6 engine that was able to churn out up to 162 hp at 180 lb-ft of torque. This engine can also be seen in other Nissan vehicles such as the Nissan Maxima and 300ZX. In fact, the Infiniti M30 had similar characteristics with the 300ZX—they were both front-engined and rear-wheel drive cars. In terms of transmission, the M30 was equipped with a RE4R01A four-speed automatic transmission with an overdrive feature that can be turned on or off with a button located on the shifter.
Coupe vs. convertible
The Infiniti M30 coupe was around 1,500 kg heavy while the convertible was around 90 kg heavier than the former. The difference in weight is due to the body and chassis reinforcements found on the convertible.
The M30 was never short of special features. For instance, it was equipped with Nissan’s Sonar Suspension II system, which furnished the car with a sonar module underneath the front bumper. This component scanned the surface of the road and adjusted the suspension settings of the car according to those readings. M30 coupes also came with standard tilting or sliding sunroofs.
Production of the Infiniti M30 lasted for only 3 years until it was finally dropped from the vehicle lineup in 1992. This was caused by its bad performance in the market. Today, this car shares a cult following with Japan’s Nissan Leopard.
