fuel injector issues ka24e rough idle
Cleaned the plugs on the injectors? You'll find a green coating on the connectors and a possible loose female end on the harness side. Then give the injectors a good cleaning. Otherwise if they're leaking, replace the 0-rings.
The exhaust problem, sounds more like they've gone brittle and busted on you. Mine are stretched pretty taut and I've got all 3 or 4 of em on. Consider getting some polyurethane exhaust hangers or the solid rubber ones by nismo.

wat should i clean the plugs with? and the exhasut only has 2 rubber hangers and tere shout be 3 or 4 but no place to put the rubber hanger. how hard it it to replace the o-rings on injectors?
You can get electrical contact cleaner at your autoparts store. Spritz some of that stuff and scrape with a small flathead screw driver. It's a bit tedious but alot cheaper than buying a new injector. Other thing is to check the female plug on the harness. It helps to bend those in very slightly to get a clean contact to the freshly cleaned contacts of the injector.
The injector o-rings are easy to replace. Drain the fuel system of pressure and pop out the injectors. When you replace the o-rings, put a thin layer of vaseline on it to keep it from shredding or bunching when pushing it back into the fuel rail.
There are 2 hangers at the very end of the muffler, almost to the end of the car. There's another one a few feet back from that one. Then there should be another one towards the back end of the piping.
