The top motor mount is worn out. It would have helped knowing the car's year, make, and model, but, if your car's engine shudders after it is warmed-up and running idle, then it is probably a symptom that your vehicle needs a tune-up (i.e., new spark plugs (assuming it isn't a diesel), change the timing belt or chain, etc) or that you used a grade of gas that is not suitable for the vehicle (in some cars, even premium gas may throw off a car's timing) or the transmission modulator (or similar) is malfunctioning. Unfortunately, without seeing the vehicle, there is no way to determine exactly what the problem is, so take the car to a qualified mechanic.
If a Zx2 shudders and dies out at stops and idle, the idle might need adjusted. If the idle is set too low, it will not maintain enough power.
If it is running fine at high revs the most likely problem is an injector
Without much to go on, I would suggest you look for a vacuum leak, especially if the engine runs good under acceleration and only shakes and shudders at idle.
An idle motor controls the idle-like when U turn on the AC,It will raise the RPM's so the engine doesn't stall. Idle motors are used on computer cars & instead of a screw adjustment.
A car can idle too low because there is a leak in the vacuum. Cracks or breaks on the vacuum hoses in the cars engine could be the cause of this.
No you cant it is controlled by the the cars computer which is set by the manufacturer
The idle control valve works by regulating the idle speed of the engine. The idle speed of the engine is usually controlled by the engine of the computer.
Most newer cars and trucks engine computers need to "re learn " how to idle after having the battery disconnected. You do this by starting the engine and allowing it to idle for 5 - 10 minutes without revving the engine. It will eventually learn on it's own if you do not follow this procedure , it just takes a little longer.Don
Cars often idle fast when you start them up. The automatic choke will make the car idles fast for a while then the idle speed will slow down, once the engine warms up.
because that's kind of a big engine
does the engine have a carburetor or is it fuel injected? A carbed engine has mixture screws along with a base idle screw, a fuel injected engine the idle is computer controlled.
Your Nissan may just idle high during the warm up of your engine. These cars are designed to do this based upon the fact the cars have an optimum running temperature. If they idle high when for the first 15 minuets it's to achieve that optimum running temp. If not then you may have a vacuum leak.
A: It all depends on the engine idle speed and cylinders. All cars at idle speed must charge the battery to 13.68 volts the RPM is a function of cinders
Since it is starting from 0, the engine idle is low.
A picture of an idle??? Idle is a state of operation not an actual part. As in, the engine is idling at 750 rpms. A picture of an engine at idle would look almost exactly like a picture of an engine that is running at 3000 RPM or shut off.
The idle speed control solenoid controls the idle of the engine when the air conditioning is engaged. Since the ac pump draws down the engine idle the solenoid increase the idle when the ac is on.
low idle and uneven idle
The engine is fuel injected and idle is controlled by the ECM (computer) on 1993 cars
No, an engine idle RPM being not zero is not a problem. If the idle were zero, the engine would not be running!
It maintains engine idle rpm when the throttle is closed.
Minimum of 10 psi at idle when the engine is warm.Minimum of 10 psi at idle when the engine is warm.
High idle, misfire, check engine light,High idle, misfire, check engine light,
On almost all cars any sensor unplugged can turn on the check engine light.
My idle was running rough and slight loss of power (5 cylinder engine). The power loss is more noticeable on cars with less cylinders.
if this happens when you first start the car it is normal. It is just the cars way of warming up the engine.
