Violent Start-Ups and Low Speed Howl Noise
I have a couple of issues that i would like to hear your opinions on.
First is when i start my car after it sat for a day or so. It's a 1.9JTDm and it seems like it will either drop right out the bottom, or fly up through the hood, the whole car shakes, and it's quite scary. Once it starts it is smooth, and runs perfect. Why does this happen? Anybody had this issue as well? I had my mechanic check the engine mounts and he says they are perfect. Why could this be?
Second is this low speed whine or howl accompanied by a slight vibration that i get at about 2000 RPM going about 50-60km in third gear, or at the same RPM in fourth gear as well. As soon as i give it gas it all goes away. And when i am on the hi-way in 5th or 6th gear at those RPM i don't get any of that. The faster i go the more it drives like it should. I remmember reading a thread about this issue, but it was a year ago, and can't find it. Has anybody had a similar experience?
The car is 2007, 159, 1.9jtdm
Thanks for your help!
