hi, i would like to know if somebody has the same problem as me. when i start and its cold outside, for about 1 minute the engine is like shaking, like he is cold as me!!! and when i arrive at 3000rpm there is like a vibration that i feel in the pedal and the sterring.... its worst when the engine is cold but still do when is hot....

 

What year is your car? I have an 08 auto and I have the same thing. Rattly, vibrating cold starts are normal for this car and engine. As long as its smooth and quiet once its warmed up you are fine. As for the 3000RPM vibration, I get vibration from 2500-3000 also. Its like the whole car resonates with the engine at that particular speed.
