Hi Oscar,
Question, what could be causing my engine surge?
My 2000 V70 SE station wagon 2.5L Non-turbo is experiencing a slight engine surge when traveling approximately 68 MPH. I also notice (at low speeds less than 20 MPH) a low base sound while accelerating from a stop sign and when the car shifts to second the base noise disappears until the throttle is activated again.
Do you think this base noise is related to the engine surging?
This past weekend I replaced my Fuel Filter & Gas Cap & the surging is still present.
Any suggestions would be greatly appreciated. Jim M
