Question
Can I have my jump starter plugged in to an outlet as if i was charging, then connect it to a batter and turn it on? Will that cha
If the vehicle battery happens to be more than 5 years (60 months) old, don't bother fooling with it. Buy a new battery and be sure the new battery is fully charged by the store before you install it, otherwise...
Question
Can you drive with a broken Variable Valve Timing Solenoid? ( Ended up splitting in half )
In some cases, the motor may run (not very well) with a broken or damaged variable valve timing solenoid, however it will likely not run for long due to the critical role the VVT solenoid plays in the timing of...
Question
My car feels like the brakes are engaging on their own when I am driving
This is normally due to brake calipers sticking. I would recommend having a brake inspection performed to determine the exact cause of this issue. Consider YourMechanic as this can be done at your home or office.
Question
What could cause fuse to keep blowing from fuel pump
Fuses are over current protection devices which means that you either have a short to ground (possibly intermittent) somewhere in the circuit or enough added resistance in the circuit that the current drawn by the pump is enough to blow...
Question
Which Gas Stations Are the Best?
All gas stations in the US are regulated to the point where there are none that sell subpar gas that could cause damage to the engine or fuel system. Every legitimate gas station will sell usable fuel, but some major...
Question
My car is still running after turning it off.
Hi there. The noise that you are hearing is commonly known as 'Dieseling'. When this happens, check the ignition switch alignment and see that the switch is turned completely off. If the switch is turned off, then while the engine...
Question
Lost half a tank of fuel in less than 2 miles. the tank is empty. can't see a leak
I would first get a 5 gallon gas can and put it in the tank to see if gas gauge registers the fuel. Then turn on the key and listen for fuel pump operation to see if pump runs. Recheck...
Question
My car stalls when hitting a bump, once stalled it takes a while for the engine to restart.
I'm going to take a leap and guess that you have a problem in the connection at the coolant temp sensor. In the older cars like yours, an interruption in the circuit at the coolant temp sensor could cause a...
Question
What type of engine oil should I use?
Engine oil lubricates the engine and helps prevent harmful friction from developing. The right type of oil is necessary as well. While all oils work in the same way, using an oil that is too thick or too thin can...
Question
When it's hot out my car won't start, any ideas?
A couple of things come to mind. I would first ask these questions: Is this a no crank or a no start? I will address both scenarios below. A no crank is when the motor doesn't turn when you...
Question
What does it mean if the Check Fuel Cap message is displayed?
A common misconception is that the only purpose of a fuel cap is for it to be a top for the fuel tank. It actually has many purposes and is a critical component of the evaporative emissions (EVAP) system. If...
Question
no crank with new starter, starter relay, battery, alternater.
If you tried jumping the contacts on the starter directly, then your problem is most likely a power or ground issue. The battery ground cable may not be making a good connection at the engine ground, or there could be...
Question
My blower motor is bad, should i replace the resistor also?
Hello. We do suggest that you replace the resistor at the same time. It may not be critical, but this will keep the system more uniform. The issue may even be related to the resistor. If you know that it...
Question
Seems to be an occasional misfire that is somehow related to the AC compressor
This is normal when the AC is on. The air conditioning compressor requires torque from the belt system on the engine to power it. When the AC is off, the compressor clutch does not activate, meaning the AC is not...
Question
Would a failing oxygen sensor cause lack of power and shifting problems?
As you may know, the oxygen sensors, which are part of your emission's system, read exhaust gases to determine whether or not the appropriate amount of oxygen is present in the exhaust. Based upon this reading, this information is relayed...
Question
How do I open the hood?
Opening the hood is very easy: 1. Pull the hood release handle, which is to the left of the steering column. This will release the hood latch. 2. Run your hands under the hood, near the center of the vehicle,...
Question
What does it mean when I put my car in gear and it won't move and makes loud clicking noise 2006 Chevrolet Malibu
Hello - check the fluid level and quality (should be more pink than black, and not smelled burned). Check also the shifter cable - the inability to re-engage Park (which is a mechanical action) suggests the shifter is no longer...
Question
When starting, car shakes and rattles and then quits
Sounds like you aren't getting enough fuel during "cold" start. First thing, check the cold start injector, and thermo time sensor, which regulates how long the cold start injector squirts. Next, check the Over-Voltage Protection relay and circuit. If this...
Question
What is the Cruise Main indicator light on the dash?
Cruise control is a valuable asset. It allows you to set the speed you want to travel and then take your foot off the gas. That can help alleviate fatigue and tension on long drives. The Cruise Main indicator light...
Question
Brown Sludge in Radiator Reservoir and Very little coolant
Brown sludge could be a consequence of mixing incompatible coolants as well as not draining the coolant frequently enough. At this point, you just want to be sure that as much of the contaminants as possible have been removed and...
Question
My car rough idles and stalls, but no check engine light.
This issue is normally caused by low fuel pressure or a faulty injector, but since you have just replaced the fuel pump, this may also be a sign of a failing idle air control (IAC) valve. This is a unit...
Question
Engine sputtering and "service traction system" control light coming on
The Powertrain Control Module needs to be scanned to see if there are any stored codes. A possible issue could be the mass air sensor, as this sets up initial injection timing. The air mass meter needs to be removed...
Question
Why do some cars with AUTO headlights not turn on the taillights also?
Hello, thank you for writing in. The automatic lights you are referring to are likely the Daytime Running Lamps (DRLs). These are an automatic safety feature that is more for other drivers around you than for your driving comforts. This...
