What kind of engine does a 1997 Nissan have?

This question came from a reader who owns a 1997 Nissan pickup truck. The small engine in this truck is similar to many other engines in Nissans and other makes. Most of them operate in a similar manner and regulate the engine’s idle speed using the same systems, so this information is useful for many car owners.

Why does my car idle at 1500 revolutions per minute?

Older cars will try to compensate for worn spark plugs or a failing ignition coil by increasing the engine idle. An engine with a problem that is idling at 1500 revolutions per minute is far more likely to stay running than the same engine trying to idle at 800 RPM.

What should I do if my Nissan truck has a vacuum leak?

Often it’s as simple as tracking down a vacuum leak, which is far cheaper than replacing your car’s engine control unit (ECU). This question came from a reader who owns a 1997 Nissan pickup truck. The small engine in this truck is similar to many other engines in Nissans and other makes.

How to diagnose engine idles too high?

DIAGNOSIS The first step in the diagnosis is visual inspection. Inspect the throttle cable and linkage for binding. Inspect the engine for vacuum leaks. With the engine at idle, visually inspect each vacuum hose on the vehicle. Listen for a hissing sound which is a key indicator of a vacuum leak.

What causes intake manifold gaskets to wear out?

As the vehicle acquires mileage, the intake manifold gaskets may wear out and eventually leak. This can cause major performance issues, as the intake manifold gaskets seal engine vacuum and pressure.

Can a bad intake manifold cause engine damage?

Engine overheating. If the intake manifold gaskets leak coolant into the intake manifold the engine may overheat as a result, without any visible external leaks. Any coolant leaks should be addressed as soon as possible to prevent the possibility of serious engine damage occurring due to a bad intake manifold gasket.

Can a leak in the intake manifold cause a bad smell?

Some intake manifold gaskets also seal engine coolant, and if the gasket wears out it may lead to a coolant leak.
