The The cruise control in your vehicle is also known as speed control or autocruise. It is a system that controls the speed of your vehicle for you, while you maintain steering. Basically, it takes over the throttle to keep...
Shaking at higher speeds is usually related to something that is rotating. Most of the time this will be the wheel and tire assembly. If you have tires that are worn unevenly, or if any of them have a manufacturer...
Hi there. This sounds like the gas pedal position sensor or the throttle body position sensor is not working properly. You can try manually resetting the gas pedal position sensor. To do this, perform the following: Turn on the ignition...
Hi there. Either the tires are out of balance and causing the front end to shake and make the steering parts move around or there is a loose steering or suspension part that is moving around as the vehicle is...
Hi there. Check the oil pressure that the engine is producing. At highway speeds, if the engine is stalling out, then the oil pressure could drop to under 12 psi. The computer will sense this pressure drop and shut down...
This is very likely a throttle issue. There is an idle control module (https://www.yourmechanic.com/services/idle-control-valve-replacement) (or similar setup depending on your make and model) that is located on the throttle body which helps the gas regulation during these moments. Otherwise, without...
Check the basics - check compression and engine tune. Check for a dirty air filter (https://www.yourmechanic.com/services/air-filter-is-clogged-inspection), dirty fuel filter (https://www.yourmechanic.com/services/fuel-filter-replacement), proper fuel pressure (https://www.yourmechanic.com/services/fuel-pressure-regulator-replacement), clogged exhaust or catalytic converter (https://www.yourmechanic.com/services/catalytic-converter-replacement). A YourMechanic professional can help with the diagnosis of your...
Hi there, thanks for asking about your 2004 Infiniti FX45. The blue smoke you notice on initial start-up is likely caused by worn exhaust valve stem seals. They allow a tiny amount of oil to get into the combustion chamber...
Hello. If this only occurs at highway speeds, then you may have pressure build up in the cooling system. This is typically caused by a leaking head gasket. If there is a slight leak, then combustion pressure will build up...
Hello. If the engine is misfiring and shutting off at this speed, then that can be caused by a number of issues. Most of the time, this is caused by a failing distributor (https://www.yourmechanic.com/services/distributor-rotor-and-cap-replacement). These are a common problems on...
Hey there, it looks like there was a problem with the link you added. However, from what you described, it sounds like the noise may be the cooling fan coming on and off as you are driving. Check the cooling...
Hello. This vehicle uses a center driveshaft support bearing (carrier bearing) on the rear driveshaft. This is a commonly known issue that I have seen go bad and cause vibrations around that speed. To confirm this, I recommend having a...
Hi there. Either the EGR - Exhaust Gas Recirculation - has been plugged up or the MAF - Mass Air Flow - sensor is dirty or damaged. Try removing the vacuum line to the EGR and test driving the vehicle...
Hi there. Try stepping on the brakes and see if the noise goes away when driving. If the noise goes away, then the wheel bearings are worn and need replaced. If the noise is still present, then there is a...
Hello. The manufacturer limits the top speed of the vehicle as a safety. The only way to be able to increase this is to reprogram the computer. This would have to be done with a custom program. There are some...
Hello. This is a speed limiter built into the programming of the computer. You may be able to find an aftermarket computer programmer to add performance to the vehicle and change the speed limit of the vehicle. Alternatively, you may...
Hello. The most likely cause of the issue that your are having would be a faulty cooling fan (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-cooling-radiator-fan-motor). The cooling fans purpose is to keep the radiator and condenser for the air conditioning cool during the idling function of...
Hi there, thank you for writing about your 2013 Audi S5. Your vehicle has electrically-assisted steering, so your car's power steering module may be causing the steering problems. Audi has a software update for the power steering module - Ref:...
Hey there. This could be due to a torque converter imbalance, or internal problem with converter, which will sometimes occur in a dynamic and limited range. Have a technician attach wireless "chassis ears" to logical areas on the drivetrain to...
Hello. This can be caused by a number of things. I usually start by checking the tire balance. If the balance is off, then this will occur. If the balance is fine, then I check the engine mounts and the...
Yes, your clutch is slipping and needs to be replaced. As for the high quality fuel, top tier gasoline does have additives designed to keep your engine and fuel system clean. Will you ever notice a difference while driving? No....
