Ok, I really some help here guys.

My engine is idling really rough, say when I am stopped at a red light. I recently had the plug and wires changed, and a new o2 sensor put on, but they didn't help. What could it be? Fuel Injectors, Fuel Filter?

Also, what would cause a mis-fire in a specific cylinder?

Please help me on this...thanks everyone.

there could be hundreds of things on this... is there any "chk eng" lights on... this will tell you if all controls are working within manu parameters... if not than there can still be an issue... you could have a malfunctioning Idle air cylnoid, or the egr vavle could be stuck open, or what about drippy injector... If you feel brave you could get a squirt bottle and spray some water on the wires and plugs to see if there is a bad wire...... or can of carb clean and look for a vacuum leak...

Just recently had a similar promblem.
It ended up being clogged and dirtly injectors.
I had the injectors clean for about 100 bucks from dealer.
If you got an ses light take it to autozone and get the code read for free.
Many of us know all about certain codes.

Yes but will dirty injectors cause a code?

Yes they can.

They produce misfire codes.

You will not be told directly that the Injector are the promblem from the ses codes being read.

However, you can still have dirty injectors with out any code until it builds up enuff and then u will get a code
