Possibly a cylinder not operating. One simple check to do in the garage is a heat test. Run a cold engine for about 15 seconds. Then check the temp of the exhaust at each exhaust port. They should have a temp that is warm to the touch on all cylinders. If one is still cold then that is a problem cylinder. Look at the wires, plugs and injector to ensure everything is OK. Further in, check compression if necessary.
If vibration starts once its placed in drive but its OK when in park then you got a transmission problem. I would suggest taking that problem to a shop. They could get an adjustment or find a more serious problem.
It is normal for a little vibration with the air conditioning on due to the compressor working , fans on , and engine running a little warmer. On at least 92-96 Toyota's the fans automatically come on when the ac is turned on
One of the main causes of feeling a vibration in the gas pedal is engine vibration. The vibration from the engine causes the accelerator cable or linkage to vibrate and the vibration can be felt in the gas pedal. Check with a mechanic to be sure.
first check engine timing this is a major cause of vibration in a stationary vehicle, or non firing cylinder could be electrical or mechanical, then harmonic balancer, then look for broken engine mount.
it cant do that because no one can stop a vibration only the earth could
No... A corolla engine is made by Toyota for a Toyota Corolla vehicle... The Chevy Prism is made by Chevy... Chevy and Toyota are different companies...
Possibly an umbrella wrapped around the flywheel?
Under the vehicle directly behind the engine.
Vibration at idle, especially with automatic transmission, is usually caused by engine idling to slow. Now, since there is no idle adjustment screw anymore you need to have the vehicle checked at your Toyota Dealer. Some vibration, even to that level is normal. IF IT HAPPENS IN THE PROCESS OF STOPPING, WHILE BRAKING, YOUR BRAKE ROTORS ARE LIKELY OUT OF ROUND.
During acceleration? I'm not sure. But when both idling and acceleration the engine's combustion can cause a lot of vibration in the steering wheel if you are in an older vehicle.
a weak battery will not cause an engine vibration.
if it is a 4wd you need to remove the engine from the vehicle
Have vehicle scanned to determine the problem
