Idle engine vibration

Hallo all, I have Chevrolete Suburban 2011 LT, since I bought it as a new SUV with 100 miles on, I have I problem with engine vibration while idling the engine. I have now 6.000 miles on and about aproximatly each 7 seconds, sometimes each 15 seconds I can feel vibration in steering wheel and the seat and it makes very unconfortable experiance to sit in the car while no motion. While driving when the car is in motion, it drives well and nice with no problems. I took it back to dealer for computer scan and did no find any problems, actually it shows that everything is OK and the engine is in 100% perfect shape. They dont know what to fix. DO you hava anybody same problem like me ??? Any suggestions what to do ? Martin, Prague..Czech Republic..Europe

It seems that's you have a rough idle. This can have many causes but the biggest would be idling to low. Or a misfire at idle. Check your sparkplug wires maybe. There are to many causes to list. As for checking fine on a scan that means little to nothing. That just tells them if specific things have gone wrong not everything. I'd suggest going to a real mechanic shop as if they find the problem you can either take it to the dealer or there may be a way to bill it to them.

SOURCE: 2004 clunking noise thru steering!

Its probably the intermediate steering shaft. The shaft where it goes thru the firewall is known for clunking on these trucks. GM makes a lube kit to fix the noise. I don't have the part number handy, but the parts guy at the local dealer will know what you are looking for.

Good Luck

SOURCE: Vibration and noise from front end while driving

Jack up the front end and put stands under it and block rear wheels. Look at axle boots and see if they are cracked. Try turning wheel back and forth sharply and see if you can hear any clicking. Problem could be outer axle joints. If the boots are cracked or you hear a clicking noise you will have to replace the axle. The axle and boot come as a complete unit. Please let me know what you find out.

SOURCE: engine shuts off while driving

I would suspect a faulty EGR valve, but is the check engine light on? If it is, take the vehicle to an autoparts store and have them use a scan tool to retrieve the fault code(s) stored in the computer. Most parts stores offer this service free of charge. That will narrow the search for the problem. Sure hope this helped.

Check your fuel pump presure. Pump is in the tank. Also try and loosen the fuel cap, the tank vent may be stopped up.

Engine has been replaced. Never had a problem with the transmission before but engine vibrates while idling and shifting all gears. Took truck to 2nd shop and they removed the transmission from the motor...


I'd be inclined to say that you have a bad torque converter. Check to see if the transmission shop replaced it, bought a new one (probably around $40.00 depending on your location), or replaced it with a used one. I'd think that the second shop would have installed a new one since they were there anyway with removing the transmission. On the off chance...the torque converter just may not be in all the way and causing the vibration.

My suburban have engine light on,got diagnoze to change camshaft sensor and crantshalt sensor but the light was still,there,wat else you think is the problem of my suv?


the check engine lite will not go out immediately unless you reset the computer. You must drive the vehicle about 100 miles to clear the ecm. There is probably nothing wrong with your vehicle now. If you use a scanner it will let you know if there are any more code left not a code reader.Good Luck!!!

2002 Chevy Trailblazer LT Oil Pressure fluctuates.


Hello. Those oil pressure readings are completely normal for you vehicle. Actually, in a vehicle with that amount of miles, those readings are quite good. It's normal for the oil pressure to rise and fall with engine speed. Keep doing those regular oil changes and you should get many more miles out of that engine.

Idle , lever on 'drive'' - vibration


if your vehicle isn't a convertible and the newer model (E90) the idle speed should be able to be increased. your vehicle has valvetronic. It doesn't use a throttle valve in the typical manner. there is a motor that changes the valve lift of the intake valve (this system takes the place of how a typical throttle works); if you have an E46 the older style 3 series the idle speed cannot be changed. An easy way to tell if you have an E46 or an E90 is that you have a start-stop button with the E90 and the key is a remote that pushed into the dash.
