Ok Guy's here's the scoop my intake gasket took a crap no big deal I replaced the gaskets and vacume line just cause they were old and cracked and now every once in a while when I go to take off or while I am just crusing down the road doesn't matter what speed I am at or wheather I am on or off the throtel it hesitates and spits and sputters. My mechanic said it sounds like it could be droping a cylinder like a plug is fouled but I pulled the plugs all of them are realy clean don't even look like they were burned . 2 of the plug boots have a crack in them I know I sound like a idot but it looks like to me that them plug boots have a outer boot and where it actualy conects to the plug it self there looks like there is another little boot in there so I wouldn't think they could ark but I could be wrong and they are arking but I can't see if they are. Any input would help guys cause I can't have this running like crap then I might as well by a chevy product thanks
