Need help trying to figure out this problem
Tranny was replaced from the dealer around 80k miles. Before I purchased the car. CL now has 103k... I took it to the dealer for inspection and they informed me warranty for that has expired.

With that being said there is a problem with the car with it sometimes not turning on properly. Once the starter kicks in the car somewhat jerks before it turns on and the rpms get really low...my car starts to vibrate really badly for a few seconds and it goes away once I drive away slowly. But sometimes my car will not start at all. I have changed the spark plugs before... battery is a month old... starter is not knocking or anything.
I know for a fact my front motor mount needs to be replaced because I have confirmed that with a mechanic... any ideas or suggestions would be helpful.

 

Yeah my car does that sometimes too. Does yours do it in park? All i do is turn the car off and restart it and its fine, i think if you dont turn the car on right, like let off the starter too early it runs funny. My car has only done it three times and hopefully thats the only three times it will do it lol
