Question about 2003 Volvo S60

1 Answer

Vibration on the floor underneath gas pedal

I have a 94 Nissan Pathfinder, 5 speed rear wheel dr. When I accelerate out of a light, I feel a steady vibration underneath my right heel. The pedal does not vibrate. It's a high frequency brrrrrr vibration that is present while I accelerate. It is most noticeable as I accelerate to 35 or so, and over 40 it is intermittent, mainly only when I accelerate. When I decelerate, it is also present, but not as much. Also, while the vibration goes on, the car's acceleration is retarded, and the rpm reads slightly higher, about 400, than usual. It really started today.

I would venture to say your exhaust is hitting your frame, or, you may need new motor mounts. The exhaust is what I would lean toward. If you can imagine your exhaust sitting under your vehicle, and the fact that the vehicle has a little age, the motor mounts probably give a little, causing the motor to move slightly on acceleration and deceleration, thus your exhaust is going to move, and may be vibrating on whatever its touching. Good luck.

Pathfinder vibration


check the "u" joints for looseness and wear especially the front drive shaft . check sliding splines . The vibration is a harmonic vibration normally associated with worn "U" joints --bent or out of balanced ---worn /seizing slip joints or being excited by a failing drive thrust bearing in the diff. ( big bearing directly behind the pinion gear that takes all the load on drive) check the magnet on the diff drain plug for metal bits.

It can be fuel pressure issue or it's the problem with accelerator pedal or its clogged filters causing there.

1988 Nissan Pathfinder, press on gas vehicle sputters then accelerates fine. Drives great but it feels like it lacks something when pressing on gas from a complete stop.


I think it would be a good idea to check your fuel filter....The most likely place for it to be mounted is in the engine compartment, or if not there it'll be underneath, close to the tank.....Regards Johngee

I have an 1989 GMC Sierra K1500(4x4)5-speed. grinds when going...


It may be the transmission input shaft bushing or bearing, located in the rear of the engine crankshaft, in front of the clutch assembly. If the bushing or bearing is dry (needs to be greased), the input shaft will still try to turn with the engine rpm, even though the clutch pedal is depressed. Also, the clutch disc may not be fully releasing, which could possibly be corrected by adjusting the clutch pedal linkage. good luck
