Hello. Thank you for writing in. The first thing you want to do it's find the cause of the oil leak, and make the appropriate repairs. The leak coming from the accelerator is likely coming down that pedal from somewhere...

There are several components to the hood release. The handle, a cable, and the latch. The handle is made of plastic and have a tendency to break over time. The cables are metal cables but they also can break. The...

Hi there. It does sound like the fuel pump may have experienced a failure from running out of gas; it does happen. You mentioned that you removed the pump and inspected it; what test was performed? A fuel pressure test...

Hello. This can be caused by a number of things. I usually start by scanning the computer for codes to see what shows up. Most of the time, this is caused by a speed sensor at one of the wheels...

Hi There, Your ESC light represents the Electronic Stability Control system in your car, otherwise known as a form of traction control. As you may know, this system is controlled by a series of sensors located at each of the...

The failure icon is caused by a problem with the traction control and will need to have transmission and ABS checked to see if there is stored codes for a sensor or component failure before a diagnosis can be made....

Hello there! The illumination of these warning lights indicates a system shutdown because of some malfunction. Since the Traction Control and ABS systems share many sensors, the fault may have to do with a sensor that is tied to both...

The EGR valve is the component that actually admits the flow of exhaust gas into the intake. The EGR vacuum controller modifies the amount of flow through the EGR valve based on the level of engine intake vacuum where the...

Hi Chantel: A big uncertainty in trying to answer your question is I do not know if the present codes, that have caused the check engine light to illuminate, are the "same" as the original codes from January and thus,...

It sounds like the cooling system is not performing as it should be. This could be due to a low fluid level, a restriction in the system, or a faulty temperature sensor. I would recommend having the coolant level checked...

Engine oil, especially oil dripping or leaking on the exhaust will create an oil burning smell. The first thing to do is to determine whether the oil on the engine is caused by a leak or due to spillage during...

You are correct that when the Check Engine light is illuminated with no drive symptoms you will not have any indicator if any more problems are happening. That is, unless another light comes on or you get symptoms you did...

Hi Taheem. Thanks for contacting us today. It depends on what you mean by "jerking". If the car is pulling to one side while braking, this could indicate a bad caliper, worn brake pads, faulty wheel bearing or even tire...

It sounds like you may have either a stretched serpentine belt or more likely a tensioner pulley that may need to be adjusted to reduce the excess slack in the belt. I would suggest having a professional from YourMechanic come...

Hi Brandon. Thanks for sending in the question today. Typically, when you replace a transmission, throttle body or other electronically operated and controlled system, resetting the TCM or ECU to link correctly with the system is a part of the...

Your remote has a battery in it that should last a few years without replacement. You should have a battery number on the back of the remote marked in the case. If not then the case has to be opened...

Hello. If you put too thick of an oil in the car, then you may have damaged the engine bearings but this should not have caused oil to get in to the spark plugs unless the oil got into the...

Hello there, many faults will cause your 2003 BMW 320i to run poorly on cold start and have a cylinder 4 misfire. You have done great in replacing the coil packs, plugs, and vacuum pipe. Common faults would be a...

Hi there - sounds like the starter "bendix drive" has failed. This is the component on the starter motor shaft that cause the starter motor to engage the flywheel as it spins up. Somewhat unusual failure these days - but...

Hi there - you have pretty-well identified this problem yourself - well done! Yes, the Automatic Shutdown Relay appears to be sticking in the "power on" position, which is providing a power path to the fuel pump as well as...

If the problem is simply no starter motor operation the fault is typically quite limited. With a fully charged battery that passes a load test, or a new fully charged battery as required, and the immobilizer (security) system off -...

If the issues only began to occur after the vehicle was fitted with a new MAF and different intake, then it may be possible that the issue is related to the recent work. The mass airflow sensor is one of...
