strange vibrating on the freeway
i know this sounds stupid,
but my car vibrates now when i reach speeds of 40 and 60 mph on the freeway. it feels like its stuttering. the engine isn't making any particularly weird noise i don't think as far as i can remember. i'll have to check that out again.
it definitely never used to do this though. i'm in the middle of some cooling system repairs so maybe it has to do with that, when i get the car all wrapped up we'll see if it still happens.
any ideas on what this could be?
