SOURCE: Vibration at 2100 rpm

It is probably your Motor Mounts. They attach the engine in 4 places to the frame of the car. When the rubber wears out, it will cause excessive veibration.

Take it to your mechanic and tell him to check the motor mounts. For the front and side three mounts, it will probably run about $550 with the parts, im guessing.

Take a look at Nissan Technical Service Bulletin NTB05-15b. Title = "Rattle Noise From Vias Power Valve Actuator / Intake Manifold Collector" This appears to describe your problem exactly. I have the same problem with my 2005 Xterra and I am going to try the recommended fix myself at home.

Don't have a good answer to your problem but the items I'd change would be the coolant temp sensor and the manifold air temp sensor if yours has one. Both will influence the condition you have posted. Also, the rpm's you noted are on the high side of safe on normal cold starts but because in extreme cold the engine oil takes a while to get where it needs to be, I'd consider using a good synthetic. It flows easier and stays on parts without draining off, giving a bit more protection.

Buick Lesaber, Lower then 1800rpm most time runs fine, Once in while surges high rpm's like driving fast 1900 & above rpm bucks /2100 smooth's out.


Need to take to a shop with a GM tech 2 or higher scan tool. These tools can actually display various sensor readings and voltages in real time and can be used while driving the car to recreate the issue. These are super expensive scan tools so most shops don't have them. Call around or bite the bullet and have a dealer do it. The money you spend on a correct diagnosis will be saved by not throwing random parts at it based on guess work.

What might be causing the problem listed below?


Could be bad ignition module as they have a low rpm section and a high rpm section. Low side may be failing as it heats up. Hard to test for this as parts store testers may not see the problem.

High Idle at Start Up


This sounds like the RPM may be a little high, but normal operation is called a "cold start routine". Like the old fashion Choke, the "cold start routine" is suppose to increase the RPM for several minutes and then decrease to running idle speed. This will engage in each "cold" start, but not on a warm engine. It is designed to do this.

Usually when an engine runs higher RPM than it is set for, it means extra air is entering the engine from somewhere. Using a spray water filled bottle, go around seams and also spray vacuum lines and the EGR pod while the engine is running. Any openings will draw in the water and affect RPM. Then you will have found the leak.

Now you can look up you exact engine on the Web and find out 2 things. If it has a 2 piece intake manifold and if it has intake Manifold runners. The 2 piece design often failed when the gasket holding the 2 halves started dissolving. The intake runners, could stick out of position and make RPM higher.

Now aside from these 2 items, you might get a Code showing that the engine is running lean. This would actually not be showing the lack of fuel, but the overabundance of air coming from the leaks.

2003 Kia Sedona rpm running high on a cold start.


If it is around 1200rpm for a few minutes this will be normal as the ECM has set the RPM to compensate for the cold air intake (much like an automatic choke). After a few minutes it should drop back to around 1000rpm and then when the motor has been running a bit drop back to around 850-900rpm. If it not following the pattern then run the fault codes and fix the sensor that is reading incorrectly.

Hi..my kia avella rpm reaches for about 1200 rpm when I start up in the morning and gradually decreases to about 600 rpm.but it takes 10 mins bfore the rpm goes down.is this normal?m And my engine loses...


Yes, that is normal operation for an engine. It needs to run at higher idle when cold and the computer does that through the temp sender. Make sure it's not excessive due to any vacuum leaks. This and the AC power loss would be exaggerated if the engine is not running correctly.

89 cutlass cierra crank but wont start when wet out unless gas pedal is pushed


This should be a drive by wire vehicle meaning it has a cable for the throttle body. First thing would be to see if any error codes can be pulled up (most parts stores will do that for free.) Drive by wire versus the late model that use electronic control for the idle have a IAC or idle air control which when first started controls the idle air intake--all air is run by it to idle the vehicle when cold--

Usual symptoms are rather high idle when cold engine or even idle and RPM jumping up and down and stalling when cold.

Another way if idle does drop when cold is tapping the gas--engine will still run until hot. Means not usually a fuel pump issue.

You could also have if the vehicle is fuel injected a dirty Mass air flow sensor, a throttle position sensor, etc.

These can be if the vehicle has them cleaned using a special zero residue spray cleaner.

First have it scanned to see what if any errors it shows--the computer.

Chevy Malibu Cold Idle Problem


Check the water coolant thermostat. If it is stuck in the "open" position you are heating up all the water in the coolant system and this will take time. The thermostat keeps the water in the engine until warmed up to almost normal running temperature, only then does it allow the coolant to enter the radiator.
