Shaking at dead stop

[Muddassir]

It started doing from yesterday. When I stop at stop light, it start shaking badly, with sound like grrrrrrr grrrrrrr grrrrrrr

It seem like either it loose fuel in the middle of each grrr or a motor that is moving as some point where it is hard for it to move further.


Any suggestion?

shaking... check your mounts...
sound? i dunno...
what year? what motor?

[Muddassir]

1992, 4 cylinder LE

Are you talking about engine mounts only or what?

[zoni]

yeah, i'd say check your motor mounts first... if you can see the motor visibly shaking front to back, its more than likely the torque strut. BUT normally when the torque strut breaks, it is caused by something else. 1. age, 2. transmission shifting poorly, 3. rough idle/poor timing, 4. hammering on the gas, 5. (if you have a manual tranny) shifting like you think you are a racer.

[Muddassir]

transmission is perfectly fine. It doesn't shake when it is running, only a few litle shaking speeds, that is like 105 KM/Hr, 118 Km/hr, and a few more including 0. The other speeds are smooth.

what options are eleminated now?

[zoni]

i'd just check the dogbone (torque strut) for cracks in the rubber. does the motor run well? any problems there? if its good, its probably just age.

[Muddassir]

Motor runs well, the feeling I have is, there is something at somepoint that is a hurdle for motor to move, while at dead stop.

By the way, where exactly is that dogbone torque strut?

check out that motor mount thread...

Are you sure the shaking at idle isn't being cause by the RPM being too low? Whats your RPM when your shaking at idle? Might just have to turn it up. The shaking at higher speeds seems to me like it could be the cause of your wheels needing to be balanced. Same thing happened with me.

[zoni]

whats up MO?????? long time no see buddy.

never turn your idle speed up! a low idle is always caused by something bigger... and when you just jack it up with the screw, it can make the problem worse.

[Muddassir]

RPM is below 1, and it go a little after each grrrrr..

I just checked it in park position, and seem like it is definetly a mounting issue. I just took a video clip of it. Let me check if I could upload it.

[Muddassir]

Well, you wont get much idea from the video clip. I will take picture of the engine.. engine move a little bit up on the access of the back of engine under the windsheild compartment.

[Muddassir]

Some engine pictures. If you could please help me out telling exactly what mount is loose.. when the engine bumps a little bit, its axis is under where 2200 is written. So it bumps more near headlights. Any suggestions?

take some pics of the rubber on this mount up close... FROM THE SIDES. check to see if the rubber is cracked.

Does this only shake when stopped at lights? Is your AC on? All my older toyotas have a similar problem, if you shift to neutral it stops. Try turning off your AC, if the shaking stops its your compressor. I've never done anything about it, just accepted it as a Toyota glitch.
