Sub 1,000 rpms my car vibrates badly at idle / park, but once i speed up +1,000 rpms it runs just fine, its only at idle, wondering if its the motor mounts, spark plugs or air intake problem.
How many miles on it? how long have you had it? it sounds like the ICS sensor . that is idle control actuator it is on the thottle body
it has 132,000 miles on it ive had for a few weeks, bought it like that but i didnt really idle it while test driving it, im not the best when it comes to cars im just learning. When you say throttle body i dont know what you mean but i'll look it up. how do i test that if it is that?
oh and would it make it vibrate that bad? if it was the problem? Out of 1k rpms it runs realy smooth
there is 2 sensors on the thottle body. 1 is a throthle position sensor and the other is the idle control actuator.cars are very fun today.there are so many sensors on them.. I have been repairs car 25 plus years,and now I just do most head gaskets and motor rebuild. I am on facebook,and some of my work is there.just getting into being online. the link ishttps://www.facebook.com/TedsRepairs

Hi
Buy a bicycle ?
You are having fun !.....................NOT !!!
no 1....Check the fuel inertia switch has not been tripped ?
The problem has to be tied in with something you have done, as it was running till you put your hands on it.
Check back at the battery and make sure you have not pulled off a connection somewhere by mistake in the vicinity of the battery.
Check your fuses with a 12v test light !
Are you getting a spark at the plugs ?
Are you getting fuel pressure to the engine ?
Do you think your cam belt has decided to give up the ghost ? have you ever renewed it ?
Hopefully you have got it running by now ?
If not, try running through these thoughts.
Good Luck !
Please give a FixYa rating, if you think I deserve it !

Idling problems may be cause buy a number of issues. You may check out the fast idle control valve and PCV if they would need cleaning. You can check out the timing it may be advanced, that is why you feel that the car runs hard.

sparkplugs are under bonnet in the top of the engine you need a plug socket to remove them but dont forget which leads go where or car wont start after

you shouldnt have to remove the manifold. you can access those plugs by removing the front tire and go in that way.
Throttle Body Cleaning on vehicles without electronic throttle control (most 2003 and down)
You can in most cases repair this slow speed stall or unstable idle by cleaning the engine throttle valve and the idle speed control valve using a product called CRC Spray Throttle valve cleaner. Spray the cleaner into the air intake of the engine with the hose removed from the throttle body, the engine will try to stall so hold up the idle speed manually. Once you have used up about 1/2 can of the cleaner stall the engine out while spraying and turn the key off, disconnect the negative battery cable for 5 minutes and then reconnect and drive the car for a about 25 miles of varied driving modes. If this doesn't cure the problem you may need the fuel injectors professionally cleaned by the dealer service dept.
