Car shakes while sitting at red light while in drive, but is fine when its in park?
Okay, I've had my 2003 Neon SE for about a year now, and I bought it with roughly 70,000 miles on it.. and now it is nearly 100,000.. probably around 96,000 now though. It runs pretty good for the most part, but there is one thing that annoys me a lot. And I notice it only does it when it starts to get warm out, so right now and in the summer.. it will be at its peak. In the winter or fall, it's not really an issue. Whenever I am sitting at a red light my car shakes a lot. Not like really vigorously but enough to be an annoyance. So sometimes I have to putmy car in park so it won't do that. So when I put it in park, it doesn't do anything, which is really weird to me. And I think it might have a connection to when I am driving on the highway, or faster than 60mph, my steering wheel shakes a lot. I thought it could be power steering fluid but it had plenty. I was told last summer that all 4 of my tires have different tread on them and I would need all new tires and an alignment, but I don't see how tires would effect a car just SITTING there? I was googling stuff and I read it could be my motor mounts? I'm not good with cars, as you can see.. I know how to put oil in, power steering fluid and check to see if my air filter is still good or not. Thats the extent of my knowledge. So if a more knowledgeable person could shed some light, I'd appreciate it.
