My 2006 Chevy Silverado Vortec Max has a rattling feeling?
As of yesterday, when I turn on my truck's engine the engine light turns on and the truck starts rattling side to side, slightly, but definitely noticeable, especially when not moving. We have checked the oil and everything is fine and the truck is cool. After reaching about 70 mph the engine light starts blinking. Any ideas about what this could be? Does it sound easily fixed by myself or should I take it in?

Hello Samantha,
I apologize that you are experiencing an issue with your Silverado’s check engine light flashing. I found this in your owner’s manual in chapter 3 page 45:
“Light Flashing - A misfire condition has been detected. A misfire increases vehicle emissions and may damage the emission control system on your vehicle. Diagnosis and service may be required.”
And then on page 46 of chapter 3:
“If the Light is Flashing
The following may prevent more serious damage to your vehicle:
* Reducing vehicle speed
* Avoiding hard accelerations
* Avoiding steep uphill grades
* If you are towing a trailer, reduce the amount of cargo being hauled as soon as it is possible
If the light stops flashing and remains on steady, see “If the Light Is On Steady” following. If the light continues to flash, when it is safe to do so, stop the vehicle. Find a safe place to park your vehicle. Turn the key off, wait at least 10 seconds and restart the engine. If the light remains on steady, see “If the Light Is On Steady” following. If the light is still flashing, follow the previous steps, and see your dealer for service as soon as possible.”
I would suggest taking your vehicle to the dealership. If you would like my assistance in working with the dealership, please email me your name, contact info, VIN, mileage, and dealership you would like to work with. Please include “ATTN GREG” in the subject line so that it gets delivered straight to me. Thank you for your time.

Sayswho's answer from CarMD is hogwash. Mr Jacobson does not know his butt from a hole in the ground about ceramics. 1000 C is nothing to ceramics. Fact: Normal operating temperature inside a catalytic converter is 1000C. The fact about ceramics is the hotter they get, the harder they get. It's why they use ceramic bearings and impellers in turbo chargers. He is an alarmist. 2800 pulses per second is nothing to modern computers. If the danger was so important to be looked at, the engine would either shut down or go into limp mode like when there is no oil pressure. Now that's something to be concerned about. Don't cry about it Sayswho, it's just the facts. I agree with Harry. Put a fresh set of plugs and wires in it then take it to the shop.
A flashing "check engine" light is a *SERIOUS* situation.
DO NOT DRIVE the truck unless it is to the dealership or reputable independent repair shop and get it fixed.
You can do serious mechanical damage to your vehicle. But don't believe me, read it here:
