Check to see if there are any stored diagnostic trouble codes. Be sure you have a fully charged battery that passes a load test. Confirm that the engine immobilizer system (security system) is not activated thus preventing the car from...
You'll have to go through a stalling diagnostic but the good news is the symptoms you are describing are fairly dramatic and so the cause is likely to be readily found. Common causes of engine stalling include a faulty mass...
Hi There, An engine misfire can be caused by many different problems and are generally caused by either a spark or fuel issue or in some cases, a combination of both. Spark related problems generally will result from things like...
Hello, thank you for writing in. The vehicle may be suffering from several different issues. In this type of situation you want to start with the least complicated option, and work your way up. Start by making sure your tires...
The two applications do not interchange in the catalog. Looking at the two in detail (using AC Delco's on-line catalog), the plugs are different, the plugs are in a different location on the unit and the output ratings are different....
Vibration at speed is usually due to dynamic imbalance of the wheel/tire assembly and/or a rim is bent. Even stronger vibration on braking can mean that the brake rotors are warped as well. Certain tire defects, particularly internal belt damage...
Hello, thank you for writing in. A P0156 troubleshooting code stands for an error with the oxygen sensor. There are multiple sensors, and this one is behind (further towards the rear) the catalytic converter. Several things may be happening. First,...
Hello. It sounds like the retractor itself is failing. This is common on this vehicle, especially as they get older. The mechanism wears out and the teeth inside of it no longer line up correctly and cause this. The unit...
It's probably an air or vacuum leak. When your foot is off the gas, at idle engine vacuum is higher which would draw in more air if there is a leak, perhaps enough to create such a noise. There's a...
Hello, thank you for writing in. The issue will need some further testing before we will know definitively. To begin, considering the symptoms, start by measuring your fuel pressure. If the pressure is weak, you want to replace the fuel...
As you may know, there are a multitude of engine oils on the market all claiming to be the "best" and prolonging the life of your car's engine. One of the main questions you will be asked when changing your...
P0174 can set if: there is an air leak after the mass air flow (MAF) sensor, such as a torn intake boot, or bad intake manifold gaskets; a dirty or faulty mass air flow sensor; a faulty oxygen sensor, incorrect...
Hi there. If you are going to attempt to complete this repair, I would highly recommend purchasing a service and repair manual for your Mercury Sable. This guide will provide you with the location of the components you are replacing,...
Your vehicle is less than 10 years old and should not have a problem getting the cable at most any Ford or Lincoln Mercury dealer. The cable may not be on the aftermarket yet and a dealer is the best...
Check the terminal/wire harness to the bulb for corrosion and loose connections. If nothing obvious appears, this fault is diagnosed by voltage drop testing which will pinpoint the segment of the circuit that has abnormally high resistance, thus causing the...
Hi Ebenezer. Thanks for writing in tonight to YourMechanic.com. I have forwarded your inquiry with our sales and service team to help streamline the process of receiving an accurate estimate to have one of our mobile mechanics replace the cylinder...
The noise you are describing could indeed be tire or wheel bearing related. On inspection, a mechanic would be able to quickly distinguish between the two possibilities. Vibration on braking is typically due to excessive thickness variation in the brake...
Hi Sandy. Thanks for all the information - it's very helpful to initially provide some technical advice. It appears as if you might have a few different things going on with your Mercury Sable. First, in regards to the engine...
Hi there. The coolant temperature sensor on most Ford (Mercury is a Ford product) V-6 engines is located on the intake manifold, front of the motor and next to the primary coolant hose. If you don't have one currently, if...
Fuel pressure may be good but the injectors should be checked for operation. At cold start, there is a temperature sensor that must be working properly to signal the PCM to enrich the mixture on cold start. Are there any...
