I tryed searching and couldn't find my exact problem, its a 91 240sx auto le, it just started idling ruff, but the rpm gauge doesn't jump around, its making a loud ticking sound from the resignator, once it gets to about 2000rpm it seems to run good, I didn't know if the cat could be clogged or maybe the resignator is clogged, or if it just needs a tune up, The noise is whats getting me. PLEASE HELP, Thanks

I have a feeling it might be your injectors.

try getting some sort of injector cleaner, or buy new injectors.

Well im not exactly sure what your problem is, but i will tell you how to check for a stuck open injector. Thats typically how injectors fail.. The symptoms you describe could possibly be one, im not really sure though.

Start up your car and let it idle. Take your injector plugs, the things with wires running from your injectors off one by one.If you notice you unplug one, and it does nothing to your idle quality, that injector is stuck wide open.
