Why does my car shake/vibrate when I start it?
I had work on my car done recently (oil change, fuel system cleaner?, engine & radiator flush). After the work I noticed when I would start the car it would shake, but only for about 5-10 seconds. It went away but it has come back and worse. When I turn the car on, it shakes hard and when the shaking goes down, I'm able to put it in drive and go. However, in the afternoons when I leave work (this happened just this week) the car will shake harder than EVER and putting it in drive/reverse doesn't affect it. When I did this the other day, the car wouldn't back out, so I put it in park and the engine revved high as if I were pressing the gas (RPM's 1k-2k). Yesterday, the car was shaking and when I put it in drive, it turned off and the brake and steering locked. It would not restart. I tried again today, got it started, it shook, I put it in drive, as I was driving the RPM's were bouncing between 1K-2K, and smoke was coming from the back. I shut it off...
