Six Valuable Tips For Your 300ZX (Z31) Part 1
- It can get really hot under that low hood and high temps will lead to short battery life. Inan attempt to deal with that problem Nissan equipped every unit with a battery shield. The shield is made of stamped sheet metal and is very effective in deflecting a good measure of the under hood heat. Most of the cars I see are missing the shield, where did it go? It was tossed the last time your battery was replaced.
- Mike, when the cold weather sets in my car is hard to start. I crank and crank until it finally starts but it idles at very low rpms for a few seconds and then cuts off. I repeat this procedure several times and then it’s ok, what’s going on? You probably have a defective auxiliary air regulator. The AAR supplies an additional shot of air down stream of the throttle plate which causes a high idle, 12 to 1500 RPM, during warm up. Replacement is the cure.
- Have you recently replaced your air flow meter only to find that the problem you hoped, or prayed, was behind you resurface? One of the most common causes of air flow meter failure is a defective air injection valve. A failed AIV will allow exhaust gas and moisture to enter the air intake stream and foul the air flow meter hot wire. It is my policy to always replace these two components simultaneously.
