Tip & How-To about Chevrolet Silverado
If you have a rough or shaky idle, the problem could be the air intake is dirty. You will need to get to the butterly of the air intake and clean it out. There is a cleaner that is sold for about $5. Use a screwdriver to help keep open the butterfly. Spray the cleaner and use a dry cloth to clean the inside of the intake. This will help to clean up alot of the gunk in and around the intake. When you first start it up it still may have a rough idle for about 20 to 30 second but it will go away. There may be even a little smoke of the exhaust but will clear up. You will have a great idle again. Great day.
