When any engine has a rough idle in park or neutral, it usually indicates that the firing order of the sparkplug wires may not be correct. A new engine usually means all new parts. Bring it to a shop and ask them to make sure the firing order is correct.
Make sure they connected all the engine mounts and the transmission mount as well.
If your car shakes while underway, your tires have worn incorrectly from misalignment. If it shakes while in park or not moving, your engine is misfiring.
You engine is probably misfiring. Check your ignition and fuel systems.
Timing belt was installed incorrect and engine is out of time.
a bad engine
possibly a broken or missing engine mount
No, not unless it is so low the engine is overheating.
because it is going on a rollercoaster of car sensations.mmmmmmmmmmmm.
this car is known to have an appearance of a rough idle even when everything is fine and a history of short-lived motor mounts
Bad engine cushions can make the engine shake. bad spark plugs cause malfunction as the car starts running.
The energy being released in the engine is not transferred to the outside; it manifests as vibration, which is transferred to the rest of the vehicle, hence the shaking of the car.
Well, voltage wise, you have a lot going on when your are cranking over the engine, so some flutter, or shake is normal.
The pistons are running in the cylinders of the engine, so when the rpm of the engine rises, the pistons quickley build up speed. It is this rapid acceleration of the pistons that casue the car to shake.
the engine mounts could be bad
Depends on the year and car it was installed in.
what does idle funny mean? Does the whole car shake? (upper engine mount collapsed) Or does the engine shake/misfire? (Intake manifold gasket)
Could be many things. Amoung them, low engine idle, one or more vaccum leaks, engine missing.
A turbo can be installed on any car with a (other than rocket) combustion engine.
Your timing belt was not properly installed. It's probably off by a tooth or two.
1997 Chevrolet Corvette.
Cylinder misfire. Possibly failed or failing engine mounts.
Sounds like you blew a cylinder in the engine.
The engine of the car may need to be cleaned or your oil may need to be changed.
If your engine shakes when you accelerate, you may have a broken motor mount. You need to get it fixed before your engine falls out of your car as you drive along.
