Q: Feeling vibrating/grinding in my gas pedal

asked by on

I am feeling a vibration and/or grinding in the gas pedal of my car. At first, I thought it was because of using cheap gas I would sometimes use, but even when I use the top grade gas, it still does it. There's no sound when this happens. The acceleration isn't smooth anymore. When I'm driving more than 25 mph, there's a grinding feeling that I can feel through my foot from my the gas pedal. The throttle body was dirty, so I cleaned that, did a fuel injection cleaning on my own (by unhooking the hose to the intake and spraying throttle cleaner in). Any ideas about what this could be from?

It sounds like you may have a wheel bearing that is dried up internally and no longer lubricated. This can cause a vibration to be felt in many parts of the vehicle. The best way to check for this is to have a certified mechanic test drive your vehicle to diagnose the vibration symptoms. Then, have them use a mechanic's stethoscope to check all four wheel bearings to ensure that they are not causing any issues. Once this test has been performed, the mechanic would then relay all of his/her findings over to you so that you can make an informed repair decision, whether it be a wheel bearing replacement, a cleaning and re-packing of a wheel bearing, etc. YourMechanic offers mobile technicians who can come to your home or office for an even higher level of convenience.

Q: Starting problem

At 180.000 miles, it could be just about anything. The P0161 and P0140 codes are oxygen sensor codes, and probably don't have anything to do with the starting issue, though you should have that investigated. The P0300 code however is...

Hello. The P0013 code very common in this engine. This is due to a bad variable camshaft solenoid on the exhaust cam. These fail all of the time. It allows the computer to adjust valve timing for better economy and...

Q: I have a vibration at 45 to 60 MPH.

The vibration you are feeling is not one of the tires since the problem comes and goes when you take pressure off of the gas pedal. The vibration is coming from the drive shaft joints or the bearings in the...
