If your car is shaking while it is idling, it is most likely your automatic choke. The automatic choke is not operating correctly but if you remove the choke and put a lubricant on it, it should stop shaking.
could need a good tune up sounds like it has a miss
If a car shakes and loses power when idling it can be the spark plug. If a spark plug is fouling, it can cause power losses.
There are a few reasons why a car shakes when idling at a red light. Some reasons could be the ignition coil, motor mounts, or spark plug problems.
Kinda need more information. Is it just when accelerating, or also when idling in drive? Does it only do it at a certain rpm or speed, or when applying brakes?
Need more info like what is the vehicle doing when it shakes, is it idling in park, driving down the road, braking, driving at highway speeds, etc.
Sounds like you ave a misfire. Could be as simple as needing a tune-up.
Your tires probably just need to be balanced.
Your car is not getting enough fuel if it hesitates to take off and shakes. The fuel filter might be plugged or you might have the wrong gas in your tank.
When the engine light comes on and the car shakes at the same time, it could be the spark plugs or ignition coils are faulty. Misfiring is causing the car to shake.
There is something wrong with it. Or you have one serious engine under the hood
you broke it and it is dead. you shall burry it in the yard
If you change your own oil it is easy to accidentally bump these off and not notice until your idling is affected. TEST IT: does your cruise control function properly?
