Hello - all of the third generation Caldinas (2002-2007) came with 4-cylinder engines, and should have 2 oxygen sensors. There will be one before the catalytic converter, and one after the catalytic converter in the exhaust system. For assistance, I...

Hey there, thanks for writing in. An initial and particular concern would be if you have an exhaust manifold leak. If so, that needs to be checked out and repaired immediately due to the hazard of carbon monoxide. Beyond that,...

From the information provided on your Pontiac, it leads me to believe that there may be an issue with your power steering pump. A test you can perform, only if you are comfortable, involves open the hood after the engine...

Hey there: It's quite possible that a stabilizer bar bushing might be the source of this knocking sound when you turn right. It's also possible that the noise is coming from an upper or lower strut mount that is worn...

Once the Range Rover air suspension starts to act up, it seems it becomes the story that never ends. You can spend a great deal of time and money trying to sort it out, but there are enough components in...

The tapping noise that you are hearing is the lifters on the engine not filling up with the engine oil either due to lack of oil pressure or they are stuck. First check the oil level and make sure that...

Engine oil pressure may be below the requirement at idle. To determine that, temporarily install an external pressure gauge and verify that you have at least 5 PSI at idle, although you should compare against the pressure specification set forth...

Hi Amber. Thanks for contacting us today. Although the cooling system of the car does not flow through the transmission, dirty transmission fluid can cause the transmission to overheat, cause more drag on the motor and increase the operating temperature...

Hi there. This is a perfect example where having one of our professional mobile mechanics come to your location to complete a steering wheel will not turn inspection is the best option. One of our mechanics can come to your...

This may be a sign of a failing idle air control valve. The idle air control valve is located on or near your intake manifold that monitors the air intake as it is mixed with fuel prior to being injected...

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,...

Vibrations, or shudders, felt while driving indicate the need for a detailed under-car inspection. The sources can vary widely. Some possibilities include: tire imbalance, tread separation, loose lug nuts, bent wheel(s). Worn/damaged/loose steering and suspension components can cause vibrations as...

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,...

You will need to be a little more specific on what the problem is you are having? Is the engine turning over at normal speed when turning to start but engine just takes too long before it will start? This...

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...

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...

Hi There, It sounds like you are describing the symptoms of a failing throttle position sensor. The throttle position sensor monitors the throttle position of the throttle plate inside the throttle body in relation to your foot position on the...

Hi. As you probably know, ESP stands for electronic stability program. If the car detects the wheels are spinning or there is a danger of skidding into a turn, it will illuminate the ESP light. If the ESP light flashes...

This may be related to many different possibilities, some of which may be related to a lack of spark or possibly timing issues and some of which may be related to a fuel delivery problem or a combination of both....

Hi, thanks for writing in. You didn't say what year your vehicle is, but I can give you some general advice. For one, the steering angle sensor will not cause steering pull. Secondly, while the power steering system can cause...

What you are describing sounds like a problem with the rack and pinion gears. The rack and pinion gear set does two things: It converts the rotational motion of the steering wheel into the linear motion needed to turn the...

Hello. There may be one of several issues wrong. When having starting and running issues, always verify that the alternator and battery are working perfectly first. Make sure the battery cables and grounds are clean, dry, and tight. From there,...
