I have a little question.
My car shaking a little when selector on "D"+full brake.
I mentioned that rpm on P or N fine around 750 but when i turn it on D it lowers to 600 and car starts to shake a little.
Also when car becomes to full stop rpms drops down to around 750-700 and after a couple of sec. it falls to 600 i dont know if thats right or no.
It never stalls and not shaking like crazzy but it's kinda buging me.
is it fine if i just turn a little screw on throtlle to add rpms or no.

maybe i should sell car now lol
Please help.

 

anyone

 

Like other vibrations, one of the first places to look is your engine mounts (are they properly tightened?). The shake-in-drive-but-not-after-juicing-rpms has symptoms that could be related to other things; but the engine mounts are pretty accessible and an easy place to start.

 

my 99 auto acts the same starts at 750 and drops to 600 (without the air conditioner on)after being stopped for a few seconds. 600 rpms compared to 750 does give a bit more vibration. on mine the vibration increases slightly when the headlights are on.with a/c on the rpms are higher and the vibration does not exist at all. when i had a bad coilpack that was a real vibration. what you saying sound pretty normal though. clean the throttle body if you havnt recently that smooths things out a little bit also
