Every once in a while,when i pull up to a red light, a complete stop, i feel a slight rumbling, shaking or vibration throughout the car. It IS noticable, but only happens sometimes. My car is 99, what could it be?

Im gonna be changing the oil soon, but thats about it. I also recently hit 60,000 miles, havent done any tuneups, but did replace the battery recenetly.

 

most likely one of your ignition coilpacks is bad

 

Whats your idle speed in drive?
Clean your throttle body, that usually helps bring back a nice smooth idle.

 

idle is about 600 in drive

 

weird i noticed the same thing the other day. the car idles fine. i jsut cleaned the throttle bottle, new synthetic oil, new pcv valve. the car is running fine.. i thought it was bc the has so much power

 

motor mount?

 

I hope its nothing serious. My friend JEEP has been doing it also. Weird....

 

ive driven quite a few auto maxs..and they all seem to have this .. including mine....go into nuetral at the light and see what happens, my vibration always go away after this...its just something the car does, not exactly sure why....I def. dont think its anything serious though

 

i have the same exact thing, and like you said sometimes it shakes, usually when the engine has been worked up. i tried to fix it, i did a tune up, throttle body cleaning, and checked for codes, it's neither of those so if your lookin to fix it, cross those 3 off of your list. most likely its the ignition coil packs(very expensive) or the motor mounts.

 

is that too low, because mine is around 900 when im stopped at a light, in park it idles at around 400
