The car dies at stop and idles rough at low rpm


OBD Tools 365 Days Shop
A rough engine idle can come from a variety of causes. During the winter months, cars may have a harder time starting and will shake when first turned on. This form of rough idle can easily be mistaken for other problems. Engine idle problems can also be attributed to malfunctioning components, such as spark plugs. Holes in the air intake valve can also cause a rough engine idle because of excessive amounts of air being drawn in.
The rough idle of an engine can signify a power loss in the car. This loss of power could lead to other problems, such as excessive gas consumption. This lack of power can also lead to additional wear on other parts of the car. Ignoring problems with the engine of can lead to a massive breakdown that will require you either to make costly repairs or replace the car entirely.

My 97 Dodge Ram 1500 is shaking when you start it and shakes the whole time its running but it will stop shaking after 2000rpm


If you don't have a check eng light on for a code to read, only three things it can be 1 clogged injector or carb try running Lucas injector cleaner 2 idle setting adjust to ness running cond 3 fuel filter and or pump they are one unit located in the tank easiest to change with a buddy by pulling the box about 12bolts and a couple wire clips lift the box off and pump is right on top inserted in the tank. Pulling the straps and dropping the tank works but harder if the tank has gas and straps maybe rusted depending on location

After the engine start running for sometime it starts shaking.


hi this could be a few things, i would check your idle as a very low idle will cause engine shaking when the engine is near stalling, idle should be around 700rpm approx when warm. If that checks out all good check the leads and that one is not getting worn and causing a misfire or a vaccum hose is not off, both will cause similar problem. The last thing i can think of is a broken engine mount causing problem as when motor idles or runs at a certain rpm it will shake harder and may be the cause aswell

When i apply my brakes my front end shakes


harder you press, the harder you shake? My guess is that you're front rotors are warped, causing unconstant breaking, causing it to pulse? Or further describe the shaking?

Would an idle control valve cause a car not to accelerate?


no, idle air control valve is literally to control your idle speed.
what happen when you press on gas? car shakes, RPM goes up, or engine just bogs down?

My car a 1987 300zx turbo 2+2 suddenly started to


It could be a couple of things. I first guess is to check the fuel filter. If it has not been changed out within 15-25,000 miles deposits that within the gas tank has restricted the flow and will cause a hesitation or very rough idle. Now the desposit could have surface close to the injectors restricting the flow. Second, tune-up ( distributor cap and button, spark plugs, wires, etc). Third, check all you fuel hoses leading (especially leading from the fuel filter) to and from the engine.If they have never been changed, I would do so. Hope this a start of resolving your problem.

Hi, I have a 2006 Altima with 31,500 miles. Recently, the engine start shaking when car is Idle but I still feel the shake when driving or at red lights. My second problem is a weird loud (humming) noise...


You don't need to change the spark plugs since it has only 31.5 K. The plugs should last 60K. There is a an adjustment at the gas cable end at engine to increase the idle a little bit. You can increase rpm at idle to 600 RPM. Since your RPM at idle is low that why it is shaking at idle, red lights. Let me know it it is shaking at high speed ( 2500 RPM)

Rough idle, Car shakes, sputters and misfires upon acceleration


It sounds like you may have a problem feeding the fuel to your engine, I had the same problem with my 89 RS. All the 1989 model's fuel systems were recalled. I think you may need a new fuel pump. The fuel pump is located inside the gas tank in the rear of the car right under the rear axle. The fuel pump itself isn't too expensive, but with other small parts such as the electrical harness upgrade and fuel filter and the labor you should be looking somewhere in the $500 range. I hope this helps.
