Fuel Injection
Fuel injection is a system for admitting fuel into an engine. Since 1990, fuel injectors have completely replaced carburetors as the primary means of getting gasoline into the engine. A fuel injector atomizes the fuel by forcibly pumping it through a small nozzle (under high pressure). Failure of the fuel injection system means poor performance and ultimately destroys the engine.

Fuel/Air Induction System Service
Using the 3pt JB fuel injection system service kit. Add can #1 to fuel to clean and stabilize fuel in tank; remove water from fuel system, clean fuel lines injector(s) and return lines. Add can #2 to oil to clean the PCV system, exhaust valves, honeycomb portion of the catalytic converter, remove sulfur deposits from o2 sensors and clean emission banks. Using the vacuum drip tool, inject can #3 into a strong vacuum source (brake boost) at 1000-1500rpm to clean intake valves and combustion chamber. Clean throttle body and MAF sensors (if applicable). Remove and replace air filter. Road test for proper operation and to allow can #2 to be pushed through the emission system under pressure.

Ignition
Your vehicle's ignition system is responsible for starting the engine by delivering an electrical spark that ignites the air-fuel mixture in the combustion chamber. Issues can involve a worn ignition switch, a faulty ignition coil or broken or corroded wiring. These problems can lead to symptoms like the engine failing to start, intermittent stalling, dashboard warning lights, or even complete power loss while driving.

Ignition Wires & Cables
These vital parts transfer the spark from the ignition coil to spark plugs that ignite the mixture of fuel and air. The mixture starts the engine. Over time, ignition wires and cables get weak and break down. This makes it impossible for the spark to reach the engine cylinders. This results in the engine misfiring. Common symptoms of faulty ignition cables and wires are: poor gas mileage, engine misfires, engine light is on, and engine vibration.

Oil, Lube, and Filter
To keep running smoothly, your car highly relies on oil, lube, and oil filters. Oil helps in lubricating, cooling, and cleaning the internal engine components. With time, motor oil becomes contaminated. Your car needs an oil, lube, and filter change every three months (or 3,000 miles) in order to function optimally.

Spark Plugs
A spark plug delivers electric current to the combustion chamber from the ignition system. Spark plugs that haven't been changed for a long time can cause ignition problems. At Cruz Auto Repair, we have automotive experts who will check and replace your spark plugs. For all your spark plug repair or replacement needs, call 510-215-1841 or visit Cruz Auto Repair today.

Spark Plug Related FAQs

How do you know when a spark plug needs to be replaced?

The most common sign that a spark plug needs replacing is an engine that hesitates during acceleration. Other warning signs may include engine misfires during startup, rough idling, sluggish acceleration, declining fuel economy, and engine knocking.

What else should I replace when replacing spark plugs?

If you're considering having your vehicle's spark plugs replaced, there's a good chance the spark plug wires should be replaced as well. Ignition wires become brittle over time, and worn wires can lead to engine misfires, poor performance, and reduced fuel economy.

Check Engine Light FAQs

What could cause a check engine light to come on?

Come by Cruz Auto Repair and we can diagnose the reasons for a check engine light turning on. It can range from something serious like a faulty catalytic converter or potential engine failure to something simple like a loose gas cap or the need for a routine 50,000- or 100,000-mile manufacturer maintenance service.

Is it okay to drive with the engine light on?

The short answer is no. The longer explanation is that the light may indicate a serious engine problem, and continuing to drive as if nothing is wrong could result in much more expensive repairs. A check engine light means you should have your vehicle inspected as soon as possible by a professional at Cruz Auto Repair in Richmond.

What is the most common problem with my check engine light?

A loose gas cap is one of the most common reasons a check engine light comes on. However, the best way to determine the exact cause is to have a technician at Cruz Auto Repair read the diagnostic code stored in your vehicle's onboard OBD computer.

What does a solid check engine light mean?

A steady check engine light generally indicates a non-emergency issue that still needs attention. Come by Cruz Auto Repair and we'll help diagnose and resolve the problem before it becomes more serious.

What does an intermittent flashing check engine light mean?

A flashing check engine light is a warning of a potentially severe problem that requires immediate attention. Get your vehicle to an auto repair shop as quickly as possible, or safely park it and arrange for a tow to your preferred repair facility to avoid further engine damage.
