The only way to rule out the battery as a cause, or contributing factor, is to perform a load test on the battery. If a battery has internal defects, even if fully "charged" it may not be able to supply...
If you are getting spark knock then you may have a bad mass airflow sensor telling the computer you are at or above 10,000 feet above sea level and would run the engine lean. Have the sensor tested. As far...
Hi there. On the VTEC engine, there are several different electrical connections that would have to be upgraded in order for it to fit correctly. But, for the same year, I believe the motor mounts are in the same location...
Sometimes there are multiple causes, or sources, of vehicle vibration. Based on your description, the vibration might be due, at least in part, to faulty motor mounts. To check for engine-mount problems, you can try shifting from "neutral" to "drive"...
Hello, thanks for writing in about your 2013 Chevrolet Spark. Yes, there should be some form of illumination there. It is more than likely a bulb issue. It should be a pretty straight forward fix which a technician, or possibly...
Hi there. It is highly likely that you have an accessory switch, relay or fuse that is damaged and causing these components to not work correctly. If you'd like, you can have one of our mobile mechanics come to your...
In order to find out if an engine is consuming excessive oil through the normal combustion process you will need to have a fresh oil change done. The vehicle engine checked and any oil leaks repaired and vehicle driven for...
Hello, and thank you for writing in. Considering the issue only happened once, it may have been a fluke. With temperatures that cold, the engine struggles to regulate fuel and spark until it warms up. When it is that cold,...
Hello, thank you for writing in. If both headlights have gone out at the same time, its unlikely the issue is a bulb problem. You may want to start by checking the fuses first. There is also a relay that...
Most engines will need at least a minimum of 100 psi per cylinder in order to run. In addition, for the motor to run efficiently, this also requires a variance of less than 10% from cylinder to cylinder on this...
Hi there. If this occurred right after an accident, then it may have damaged the wheel speed sensor. If you have the spare tire on the vehicle then this can occur also. Usually when this problem starts happening it is...
Hi there - no, blocking the exhaust will not damage valves or lifter. It will, however, cause your engine to lose power quickly (minutes), depending on how severely the exhaust is blocked. Think of the engine as an air pump,...
Hello, thank you for writing in. Your vehicle should be fine for 2 weeks. If you think there is going to be an issue, you can disconnect the battery cables so the vehicle cannot drain it. This may reset some...
Hello. If all of the air is out of the system then the issue is internal. It is typically caused by a blown head gasket. This can occur when the leak is really small. When it is small enough the...
The fuse box on most vehicles, including the Commodore wagon will be located on the driver side of the dashboard, located next to the steering column. You can access your vehicle owner manual or search online for a fuse diagram....
This is usually caused by a valve body or leaking pressure inside the transmission. The transmission would need a complete check with the correct scanner and pressure testers to find the cause of your problem. I would recommend having a...
Hi there. The difficulty in starting your vehicle maybe from a worn out timing chain/belt. Also, the difficulty in turning your steering wheel may be due to a failure in your power steering system. The humming noise while driving can...
The engine ignition system should be checked for misfires and fouled spark plugs and shorting plug wires. Have the engine computer scanned for any stored codes for the MAP sensor on the engine intake. These are know to fail and...
Your car’s wipers provide you with the ability to see clearly out the windshield during inclement weather, as well as to operate the windshield washer system to clean the glass. Here’s how to use them: The ignition must be...
Your Turn Signals provide important directional information for drivers behind you as well as those approaching you. They tell other drivers that you’re about to turn, so they can expect to slow down and will begin backing off (it also...
A scratching or scraping noise when hitting the brakes is the first sign that your brakes are worn out and may have hit "metal to metal", meaning there is no brake pad left and you need new brake pads. A...
Be sure the battery is fully charged. "New" batteries are not necessarily fully charged at time of sale. Of course, confirm that the engine immobilizer system (security system) is not activated. With the key held in the "start" position, you...
Hi Emil. Thanks for contacting us today. I'm a bit confused by your question. if the FM modulator is not working now after the spark issue, then it's likely that the short circuit has damaged electrical components inside that system....
Hi There, It sounds like you may have a weak connection or a short somewhere causing the excessive power draw on the electrical system. You may also want to check the voltage regulator to see if it is allowing the...
It sound like you got water into some of the electrical connections from the water that is sprayed sideways and from the bottom of some of these car washes. Also, your car was running, which could cause the water to...
