So, just got back from Phoenix and had a terrible drive back!
At first I thought maybe it was just the road, but after about 50 miles, I determined, naw it's definitely the car. At any rate, the entire 340 or so mile trip I had this wicked vibration (almost like a stutter) through the entire car- I felt it in the steering wheel, the dead pedal, the floor board and could even see the passenger seat vibrating like crazy (could feel it for sure when I put my hand on the seatback).
Some of you may remember that I posted a thread a while back about a very fine, rapid (almost machine-like) vibration I'd feel in the gas pedal between 3k and 4k rpm's, which the dealer said they couldn't feel. Well, I'm wondering if this little demon has grown into something worse!
I didn't hit anything, didn't run over anything and didn't change anything on the car after arriving in Phoenix. Drive there was perfect - no car-wide vibration and the car actually sat for the day until I came home today.
Of course, first thought is tire out of round or unbalanced, but seems a bit random to just happen!
Any thoughts as to what this entire vibration is? I'll tell you, I felt like I was driving an 82 Camaro and pushing it to go 85mph rather than a Porsche that should feel fluid at 80mph (actually I'd expect the damn thing to feel fluid at 145mph). But I'll tell you, it felt frickin unstable even at 85mph! I'm not too happy right now!!
