01 gt. no motor mods, just exhaust. Idle dosent sound smooth. There is a small "bump" or miss in idle. Car runs and drives great though. Sometimes when i start it, it will start and die. Upon re-start, it starts fine and continues with the shitty idle. Any ideas? just changed plugs and oil. Im thinking egr or somthing along that line.

check for vacum leaks. a little carb spray or brake cleaner sprayed in there should do the trick.

Sounds like it has a injector problem to me...Could have one thats leaking when sitting and that could be causing the starting problem when cold and the random miss at idle......If it is a 01 put a scanner on it.It should store a random miss fire code,if it does try moving the injector to another cylinder if it follows the injector change the inject.If it doesnt then try moving the coil pack...
