Like I say I have 1998 Infiniti Q45 that In bought used a year ago. The only humming or buzzing I have heard is what sounded like the third break light buzzing a couple of times driving down the interstate. The car seems a bit sluggish at times, under acceleration. Yesterday, I got the oil changed with the usual Mobil- Synthetic. Two hours later, I drove 22 miles round trip to town. I drove about a mile to a stop sign, pushed on the gas midway, and the car stumbled once for about two seconds, then everything was fine. When I was a mile back from the house, I hit the gas down to the floor, and took off great, but acted like it was cutting out about three times, for about a second each. Is this the classic signs of needing to replace the fuel pump? And if this is the fuel pump, will I need to replace the fuel pump pressure control unit, that I have been reading about in other articles?
