eddieo818 Posted May 2, 2008 Report Share Posted May 2, 2008 What's the sea foam trick? go to your local auto parts and get a bottle sea foam its an addative pour it all into your gas tank only if you have 1/2 a tank or more it should clean your fuel injection out and the other is through your vacum line Quote Link to comment Share on other sites More sharing options...

silverss05 Posted May 3, 2008 Author Report Share Posted May 3, 2008 Well the truck has been at the dealer for 2 days now and they couldn't find anything wrong. They said everytime they go out and drive it it never does anything i describe to them. So I guess I'll wait and see if it does it anymore. I have an AEM intake, could this mean its time to clean the intake? Quote Link to comment Share on other sites More sharing options...

SS_bnoon_SS Posted May 7, 2008 Report Share Posted May 7, 2008 where is the vacum booster diaphram? The big black round thing on the firewall in this pic (even though it's a pic of a newer silverado, the booster looks the same). Be sure to check the hose leading from it back to the intake too. It's a bitch to replace a booster if you've never done one... Quote Link to comment Share on other sites More sharing options...
