The limp home mode helps protect your transmission if damage is detected. Limp home mode limits the transmission to only second gear, which keeps your vehicle safer, while also giving you enough power to get to a dealer. If you...
Yes, you can use a MAF cleaner on a throttle body, but you cannot use throttle body cleaner on a MAF. The MAFs are very particular. If you use the wrong kind of cleaner on the MAF sensor and it...
This is a notorious issue with this model of Impala. The noise you are hearing is most likely the blend door actuator attempting to move to its default position but is not able to do so. This repair usually requires...
Hi There, This is completely normal for the oil pressure to increase when accelerating. The oil pressure inside the motor increases as the motor works harder. Your oil pressure switch reads this change in pressure and relays this to the...
Hi, thanks for writing in. It is possible that you could have accidentally spilled a little bit of oil on your serpentine belt. If this is the case, the noise will eventually go away. If it does not, you can...
The first thing you want to do is make sure the bulb is actually burned out, that is the filament tests "open", as opposed to a situation where you have a good bulb but a bad terminal connection. You'll need...
Hi there. Today's modern automatic transmissions are much more complex than in years past. Because of this, your shifting issue may be caused by several individual internal components such as the ring gear, central gear, or even the torque converter....
There are a number of things that may cause the car to hesitate when accelerating such as low fuel pressure, a dirty or faulty mass air flow sensor, clogged or dirty fuel injectors, a faulty throttle position sensor or potentially...
Hello, thank you for writing in. Typically when the wipers are having these types of issues, the spring in which pulls the arm to the window is weak or broken. You can test this by comparing your wipers to wipers...
The most common cause of the fuel system not holding pressure up to the injectors is the fuel pump inside the fuel tank. The fuel pump has a check valve built into it that is supposed to keep pressure to...
If you are not experiencing drivability issues, the catalytic converters may be starting to become inefficient. Catalytic converters often times are ruined by raw fuel in your exhaust system. Misfires that go unresolved are usually the cause of this. A...
Hello, thank you for writing in. There are pedal extensions on the market you can purchase to raise the pedal up higher. Typically there are other ways to adjust the pedals as well (typically for performance or handicap purposes). These...
The oil pump in your transmission is probably worn out. The oil pump produces the hydraulic pressure that the transmission uses to engage the forward clutch. As the transmission warms up and some of the clearances tighten up, there is...
Hello. From what you describe it would appear that your vehicle may be shifting late or slipping. The first thing I would do is check the transmission fluid to see if it may be low or dirty. If the fluid...
Hi there. It is okay to replace a catalytic converter with using clamps and sleeves. However, you will need to make sure that there is no exhaust leaks. An exhaust leak before any oxygen sensor will cause the engine light...
The vehicles systems can be reset just by disconnecting the battery for an hour and all fault codes are usually cleared once the power is disconnected. however, this will not clear any problems with the vehicle. If there is a...
Hi there. Check the engine for any oil leaks that are visible to you. Check the front seal, the oil pan, the oil filter, the oil drain plug (make sure its tight), the valve cover gaskets, the oil cooler lines,...
Hello, I believe what you are describing is a problem with your PCV valve. A bit of oil in the throttle body is not going to harm your motor and is certainly not going to cause it to blow up....
Hi there, if work was recently done on the master cylinder or brake booster, check to see if the brake push rod (manual or power assisted) has too little free play. If it is too tight, the master cylinder piston...
The temperature of the climate control system can be set to either Fahrenheit or Celsius. To do so, press and hold the Mode button. While holding this button, press and hold the Dual button for at least three seconds, at...
Hello. If the RPMs drop off right as the engine is stalling then the most common cause of this is a bad crankshaft position sensor. This sensor tells the engine computer what the engine RPM speed is and what...
This is somewhat normal as the oil sits down in the oil pan when the car has sat for an extended period of time. When you first start it in the morning, it takes a bit of time for the...
The rearview mirror has two settings: day, and night. The night setting is designed to reduce glare from bright headlights, and should always be used at night. It also provides less clarity, so it should never be used during the...
Hi there: Although it's possible that a faulty brake switch is the reason why your Altima won't start, it's also possible that the starter, starter relay, ignition relay or ignition module on your 2009 Nissan is damaged or faulty. The...
Hi there. The oil pan gasket could take from 1.75 to 2.50 hours depending on the technician that is working on the vehicle. If you are not a mechanic and are wanting to change the oil pan gasket and have...
