Check for a vacuum leak on the engine. A vacuum leak will cause the engine to rough rough and stall out when the engine is cold or hot. If there is no vacuum leak, then the Mass Air Flow Sensor...

The oxygen sensor heater is integral to the sensor assembly itself. It is not separately serviceable. If the heater tests bad, the entire sensor is replaced as an assembly. In your case, P1193 refers to an oxygen sensor which is...

Hi there. The codes p0300 (https://www.yourmechanic.com/article/p0300-obd-ii-trouble-code-random-multiple-cylinder-misfire-detected-by-jamahl-walker) and p0303 (https://www.yourmechanic.com/article/p0303-obd-ii-trouble-code-cylinder-3-misfire-detected-by-spencer-clayton_2) are for the engine having a misfire. P0300 is for a random misfire where p0303 says that cylinder 3 had a misfire all the time. The code p1314 (http://obdii.pro/en/code/P1313) means that...

Hi there, thank you for writing in about your 1997 Jaguar XJ6. The poor mileage and a rough idle is potentially due to a bad coolant temperature sensor (https://www.yourmechanic.com/services/coolant-temperature-switch-sensor-replacement) or a broken wire to this sensor (the coolant temp sensor...

The "stiff" gas pedal issue (https://www.yourmechanic.com/services/gas-pedal-is-stuck-inspection) is most likely caused by a dirty throttle body in the air intake system. Cleaning the throttle body (https://www.yourmechanic.com/services/clean-throttle-body) should relieve this symptom. The lack of "Drive" selection, unless first selecting "Reverse", could be...

It is possible that your Exhaust Gas Recalculation system (EGR) is faulty, and is venting exhaust back into the engine at the wrong time (during idle). There is a Recall for you year and model (T493) relating to a problem...

The trunk has two fuse panels one on left rear and one on right rear of trunk area. The one on the right has the fuel pump relay and fuse. The trunk door lock is in series with all the...

Typically, the braking system friction material should be inspected at every tire rotation. The parking brake is integrated with the rear brake calipers. When the brake pad friction material wears down to a low measurement, or the pad's thickness warning...

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...

Hi there. Circuit 1 failure means that there is a blown fuse in your fuse box. Look in the fuse box for a blown fuse and replace it. The circuit may relate to the transmission shift module. If you replace...

Hi there. In most cases, a malfunctioning brake light will not trigger an error code that renders the engine non-compliant. What may be the cause of this issue is if the transmission gear shift solenoid (https://www.yourmechanic.com/services/shift-interlock-solenoid-replacement) or neutral safety switch...

This might be the idle air control valve failing (https://www.yourmechanic.com/services/idle-control-valve-replacement). Since this is one of the electronic engine controls which interacts with the engine management system to control idling specifically, it is a prime candidate for this mode of failure....

Hi there, thank for writing in about your 1997 Jaguar XJ6. It sounds like the alternator drive belt (https://www.yourmechanic.com/services/alternator-belt-replacement) (accessory belt) is loose, glazed, or worn out, and should be replaced. A second possibility is that the belt tensioner (https://www.yourmechanic.com/services/drive-belt-tensioner-replacement)...

The transmission cooler lines go into the radiator to keep the transmission fluid cooled. It may be possible that the engine radiator leak has caused the transmission to get hot and now the transmission front pump seal or front shaft...

Hi, these cars have developed many idle issues over the years and there are a few things to check. All the linkages for the throttle should be inspected to make sure that when you release the pedal, the return spring...
