Question about 1996 Chevrolet C1500
Before you due the following procedure , make sure you have NO SES light on , located on your instrument panel . Service Engine Soon light or Check Engine light is what I'm talking about . If the light is on , have someone obtain the codes from the EC M. memory and correct whatever is causing the codes to be displayed . Also, make sure the codes are cleared after the repairs are done or the computer will keep the EEC system in limp mode or what is called "open loop". We want the system to be in "closed loop" which is allowing the computer to control the fuel delivery as it does when everything is working correctly . Then, drive the truck and see if the noise is still there . If it's not there anymore , great !!!! Problem solved. But, if it is still there, making the hammering noise, then proceed to the following steps .
Drive your truck until it gets real close to "E" on your fuel gauge . Then , do the dirty deed , LOL..by purchasing $10.00 worth of the highest grade fuel at the pump, whatever it is . You want the highest octane rating selection and it will be the most expensive selection . Drive the truck as you would normally giving the high octane fuel time to mix with what little fuel was still in the tank when you added the high grade fuel . Personally , I would reset and drive at least 50 miles on my odometer "TRIP" feature to allow plenty of time for the high grade fuel to work its way completely into the entire fuel system and engine . Then I would listen to my engine to see if the noise has either changed considerably for the better , or perhaps completely disappeared . If either of these occurs, change the spark plugs to a cooler range as detonation is probably the source of your noise.
