Car shakes when I start it?

[blackhawksfan18]

I've looked online to find an answer and people are saying that it could be spark plugs/wires. Basically the problem is that when I start my car (Cold or warm) it shakes then is normal. Could it be the plugs/wires?

elaborate? Does it start right away? RPM drop after it turns over?

Any CEL codes? If it was misfiring, CEL is probably on.

is it a shake or vibration ? could it just be that the higher rpms are causing a vibration as it tries to warm up ?

No CEL or codes as far as I know. I'm might be going to AutoZone tomorrow so maybe I'll have them run a scan in case there is anything.

It only does it once the car starts not as it's idling. It usually does is more violently during cold temps (Anywhere from negative to about 20-30 degrees). Also, on really cold starts I hear the car whistling. Is that just is trying to get warm? I have a tendency to over think things with my car so forgive me if I'm describing something normal

Sounds like what happens to me. The RPM drops low every time i start the car then comes up. When it drops low, the car does shake quite abit. I wouldn't worry about it though.

My rpm's start high 900-1000 then drop down to 750-800.

That's normal .. your engine's just idling higher when you first start it so that it can warm up .. if the shaking goes away after it's warmed up then you're fine .. unless it's VIOLENTLY shaking, that's another thing .. either that or your motor mounts are worn but I doubt it.

Thanks guys for your input. Like I said, I tend to over think things so I'm glad this is normal.

By the way, what are some other signs of bad mounts?
