Feel like I'm posting so many questions today..
Here's the deal. Occasionally (although more frequently everyday) when I start my car (98 V6) up, the engine shakes, but only a little. On these occasions, when I put her in reverse, the shaking gets RIDICULOUS, and it gets even worse when I give it gas. When I put it in drive it slows to how it was in park. Then the shaking slows to how it was in park, until I give it some gas, and then it goes away. I have no idea what the hell is wrong. I checked the coolant today, because my AC doesn't work. It looks to me to be empty. No idea if that's relevant to either the AC or the shakes. Or I could just be a fool, and be misreading the coolant level. No idea. Any help from someone experienced would be appreciated. I'm just a stupid teenager.
