Hi there. Typically when you hear a click sound when you turn the key, and the battery and starter are new, it's due to a faulty ignition or starter relay. I would check both relays and also fuses first, as...
You either have a leaking injector that is dripping fuel after you shut off the engine and causing a flooded engine and will cause the hard start and erratic running conditions. You could also have a fuel pressure regulator or...
Hi there. Water leaks can come from various sources: a clogged drain tube in the AC/Heater box can cause overflow through the heater vent, or faulty cowling can cause water ingress into the passenger compartment. Once the source is found,...
Hello. You have 2 separate problems here. The P0191 (fuel rail pressure sensor circuit problem) may just be a symptom - it is reporting suspect fuel pressure on the rail. The fuel pressure on the rail is controlled by the...
Your car has an automatic transmission and will automatically downshift as the speed of the vehicle slows down. This spike in RPM's is just the downward gear spinning the motor up slightly as it downshifts. Nothing to worry about as...
Hello. Most of the time a jerking is caused by an engine misfire. If the engine has not been tuned up in some time it may be as simple as that. It can also be caused by a sensor that...
Hello, As a general rule, car engines do not like cold weather and will generally require more fuel in cold operating temperatures. When you start your car in the morning and turn the key to on, the coolant temperature sensor...
Hi Roger. Although it is possible that your catalytic converter might be wearing out, it's most likely not the source of your oil pressure problem. Typically when an engine develops excessive sludge (caused by carbon deposits from burning gasoline) will...
Hello, thank you for writing in. The noise you are hearing is not normal, and can be the result of several issues. Most likely you are hearing a belt squealing due to a bad pulley, tensioner, or other similar component...
Hello. If the system is leaking coolant then the leak needs to be found immediately. If it is leaking from around the transmission area then it is usually either the external pump or the inverter. These inverters are a common...
Hi Mark, There are a few things that can cause the shaking and engine light to come on. Generally, this happens when there is a misfire due to a spark problem or an over or under fueling problem. Things like...
Hello, thank you for writing in. There are several causes for high idle after starting. The first thing to consider (although it has its limits), is that the engine does need more fuel when cold. This is why all cars...
This code relates to the pressure control solenoid that regulates the pressure of the transmission fluid flowing in and out of the valve body inside the transmission. Generally, this is usually related to some kind of foreign material that gets...
Hi there. A blown head gasket is typically the result of an overheating situation, not the cause. So, if your engine has been overheating recently, it's possible that engine damage has occurred. However, it is more likely that the radiator...
You need to verify the shift cable has not come off the transmission causing the car to not be in park so it can start. If this is okay then you may have a theft system problem if light is...
Check that all fuses are good. You can try removing the electrical connector on the back of the instrument cluster and plugging it back in. Odds are, the amplifier inside the gauge cluster has failed of has poor connection. It...
It's hard to say what happened first, but the coolant tells a story of a leak. Of course a coolant leak can cause overheating, or overheating for some other reason can cause a coolant leak. You may have spilled coolant...
When your battery died, so did the power to your radio. This activated an anti-theft feature built into your radio, which puts the radio into a "safe mode" every time power is removed from the radio. This could also be...
Hello, thank you for writing in. Without the codes that are present it is hard to narrow down the possibilities for you. Coil packs and fuel supply are going to be towards the top of the list. You should start...
Hi, thanks for writing in. The insurance company can use "diminished value" for a number of reasons. The overall condition of the vehicle not including the wreck, above average mileage, etc. I would ask them what criteria they are using...
Yes, it certainly could be. Of course, the first thing you'd want to do is have any good mechanic check your battery and your alternator. There is a load-test that the mechanic can do; YourMechanic guys can do it and...
Hi and thanks for contacting YourMechanic. It seems that your vehicle has a wheel bearing that is grinding causing the noise that your are describing. Raise up the vehicle where the rear wheels are off the ground and the front...
Hello. You are correct that the light can come on for these reasons. If the oil light comes on and there is no engine noise then it is more than likely the oil pressure sensor that needs to be replaced....
Hi There, It sounds like you may have a faulty 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 gas pedal. Based...
