mc teg Posted April 21, 2007 Share Posted April 21, 2007 I need some help with this problem. Whenever I start my LS cold, it idles around 1300 in park and shakes around 900 in drive. When I am driving, it drives fine till you let off the gas. When you let off the gas, it starts surging around 400 rpm. When I am slowing down around 10 mph, the engine dies. I just replaced the fuel injectors about a month ago. Can this be fuel related or air related? Quote Link to comment Share on other sites More sharing options...
mc teg Posted April 22, 2007 Author Share Posted April 22, 2007 I noticed a hissing sound from the egr system. Could it possibly be that the egr valve or gasket needs to be replaced? Quote Link to comment Share on other sites More sharing options...
VMF Posted April 22, 2007 Share Posted April 22, 2007 high idle is normal, try waiting until engine warmes up coomletely and then drive. check if there are any differeces, when you see that the engine is about to stall, rev the engine up to 4-5k rpms and see if that helps. let me know the result:) Quote Link to comment Share on other sites More sharing options...
