No, it is not normal for a newer car to idle and shake rough. I have had the same problem with my car and all it required was a tune up and a change of the spark plugs. I work for General Motors as a Licensed Mechanic. I encountered a sitution on numerous occassions where one of two problems existed. First, if the alternator had been replaced and the harness (sensor array) had not been properly re-routed, vibration caused the injector set harness (back left of the fuel rail), to rub through on the alt. mounting bolt causing a short to groung on one of the injectors resulting in a misfire, excess O2 down stream, compensation through the O2 as a lean condition, and ultimately the IAC trying to compensate with increased air. The second most common problem resulting in over idle speen a vacuum leak into the intake. Either through the crank breather vent or failed phlenum gaskets. Either condition tends to flip the SES with a 'high idle' or 'rich mixture' fault.
Idle speed will vary from 600-1000 rpm.Idle speed will vary from 600-1000 rpm.
A typical idle speed for a normal car engine is 600 rpm to 1,000 rpm. It is higher for buses and motorcycles. RPM stands for revolutions per minute.
600 to 1000 rpm, will vary by what the computer is aiming for.
No. It should be idling around 650 warmed up. Look for a possible vacuum leak.
anywhere from 800 to 1000 RPM.
it should be 1000 rpm
Im guessing your asking @ what RPM is the 4 cylinder engine supposed to idel at. Well, theres usually two idle settings. A cold idle and a warm idle. You didint mention for what engine, and that's important because every engine has its own correct idle but to give ya a rough idea, the cold idle is usually 950-1000 RPM and warm idle is usually 850-900 RPM!
Will vary between 700 and 1000 rpm.
Idle speed is automatically controlled by the PCM. It varies from 600 to 1000 rpm. If it is not in that range then it has an electrical problem or a vacuum leak.
Turn the idle adjustment screw on the carburetor counter clockwise while the engine is running, until the engine idles between 950 and 1000 RPM.
when u first start the car it will idle high, around 1.5 rpm to 2 rpm. when its warm up it should idle between 700-1000 rpm
Normal is 20-30 psi at idle. 40-60 at 3000 rpm. Minimum at idle is 10psiNormal is 20-30 psi at idle. 40-60 at 3000 rpm. Minimum at idle is 10psi
It is normal for a GMC Sierra to idle fast when it is first started. It will idle at around 1500 rpm until the engine warms up. To get it to slow the rpm's sooner, a person can tap the throttle once and it should slow down.
when the engine starts and is warming up the idle is supposed to be at around 1500 rpm but when the engine warms up the idle should drop to between 700 and 1000 rpm. if it doesnt drop then see a mechanic because it is a very complicated fix
It maintains engine idle rpm when the throttle is closed.
Disconnect the battery and then reconnect it. This wipes the engines ecu memory and the engine needs to relare thing. So if you allow the engine to idle at about 1000 rpm it will stay that way.
10psi is minimum. Normal would be 30 at idle, 60 at 3000 rpm.10psi is minimum. Normal would be 30 at idle, 60 at 3000 rpm.
Simple, in D or any other forward or reverse gear you are putting a load on the engine by activating the transmission. N or p are neutral gears that put no load on the engine and that is why you can take your foot off the brake in either one. The question is what is the normal idle rpm of your vehicle? If it is out of range then it must be adjusted.The normal idle RPM of Neon is 1000. It just went up to 1500 when I stop at the red light yesterday. It was 1500 rpm on both N and P. It's never been like this. I think something is wrong.
Idle speed could be 550-900 rpmIdle speed could be 550-900 rpm
About 600 RPM
vacuum line is loose or disconnected. look for a small hose in the engine compartment that is like that
Idle speed is normal.
Most cars typically idle between 400 to 1000 rpm
