In response to the motor with the bad shake its a 1992 240sx ka24de 2.4 liter dohc 4 cylinder just did a motor swap shakes really bad during idol when the motors warm its still shaking?

In general, engine "shaking" is caused by a misfire in one or more cylinders. That can be caused when a multiport injector is plugged or faulty, a plug wire or sparkplug is faulty or one or more cylinders have low compression. Try to isolate the cylinder that's not firing. Plastic pliers are available for pulling plug wires. Pull one plug wire at a time and see which one DOESN'T make a difference. When you pull the plug wire from a cylinder that's running, that cylinder will stop firing and the engine will run worse. If you come across a cylinder that was already misfiring, the engine won't run any worse by disconnecting the plug. Once you've isolated the cylinder, check the plug. If it's fouled or wet, it's possibly an ignition problem, check the wire(s) and possibly replace the plugs. On the other hand, while you have the plug out, check the compression on that cylinder, it should be above 100 PSI, or at least very near to it. If the plugs are good, and the compression is up, start being suspicious of the injector.

BMW 318i when you start the car it starts shaking but when you press the accelerator it stops shaking but when you take the foot off the pedal it starts shaking again?

One or more cylinders on one side is/are not firing. Check by pulling a plug wire while the engine is running. If there is no change when you pull the plug wire than that cylinder is not doing anything. Replace the plug wire and pull another until you find the one that, when pulled does not affect the engine.

Why is your Toyota echo engine shaking?

Could be any number of reasons. First if the check engine light is on, make sure you read the codes which will give you clues as to what is wrong. It could be a misfiring cylinder, bad/dead spark plug, warped cylinder, damaged or missing motor mount, or even a damaged/worn timing chain. A simple cause would be bad fuel or water in fuel, or a clogged air filter. Check your oil level, spark plugs, and air filter first, these are easy and inexpensive to replace.

How does the kink in a mercury or alcohol work in a clinical thermometer?
