Angry My car VIBRATES(SHAKES) in idle, its driving me crazyy!!

ok so here's the dealio, whenever i come to a complete stop or i am in a red light my car shakes(vibrates) and i can feel it everywhere its bugging the crap out of me, once i press on the gas it goes away! also this happens once the engine warms up, when its cold it doesnt vibrate(shakes)

so far i have cleaned the throttle body, cleaned the pcv valve, the maf sensor, and also inserted a fuel injector cleaner into the tank.

*edit* it is a 2000 TOYOTA COROLLA VE, WITH 81,600 miles

sounds to me that your motor mounts are worn. when your car is cold it is at a faster idle till it goes into cl and idle will drop hence making your car shake. ive replaced a bunch of motor mounts for corollas for that complaint. gl

1. Buy a Haynes manual if you don't have one. It's only like $15-$20. I'm a Post-Bac Grad now and even I bought one as an undergrad.

2. Look at the mounts. See if they're worn out. Search the forum, there's been some talk about how to look at the mounts.

I gave you my professional opinion, from my 10 years as a dealer mechanic. Dealing with all the issues with corollas from late 90's to early 00's from belt tensioners, leaking oil from head gaskets, cat converters just to name a few. It's that from your description it sound as if the mounts are worn. By any chance did you or someone scan yout car with a toyota scan tool? it has a lot of features that most inexpensive generic scanners don't have. Read the data list and see if all the data in the ECM is within spec. Thats where i would start. Did u reset the computer after you cleaned the mass air flow and tbody, when u clean those componets the computer only remembers what it had learned with all the build up of contaminats like carbon, dirt and the elements of earth,lol. Your computer will relearn after driving it a bit, but will learn new values faster if you pulled the EFI for a few minutes to reset back to stock parameters. All though It could be anything or multiple issues one could never truly know only suggest possibles without actually looking at it. GL and lets us know what you come up with.

i had the same problem. if you notice your gas burning a bit faster, it may be a loose fuel injector, it happened to me. to be sure just remove the cover and press on each injector and tie one of those cable things that are used to tie cables together and never come off. loose fuel injectors cause a strong vibration when cold.. thats my 5 cents

compression

do you notice white smoke coming out of your exhaust ever?
If it is a problem with a certain cylinder you can isolate it by taking out a plug
one at a time while the engine is running, and see the difference in operation.
Get a compression check if you are able to isolate your problem to one cylinder.
