93 Camaro 3.4 rough idling

I have a 93 Camaro with the 3.4 it started to idle rough and and misfire when I gave it gas. I have changed plugs the DIS the fuel filter but the problem is still there, there is no codes so when I scan it nothing shows up. I also changed the wires and no better results I read in forum something about some wires on the left side head that break over the years. Does that sound familiar to anyone? Thanks

i thinking those wires that break are the engine ground straps. strong possibility you have injector problems. just a thought tho.

Yea, sounds like it is fuel related. Check fuel pressure then check your injectors.

"Here are a list of some of the symptoms you may be having caused by poor fuel distribution by faulty fuel injectors.

(1 Hard Starting
(2 Poor fuel economy
(3 Rough Idle
(4 Car runs fine when cold and terrible when warm
(5 Car will start just fine when cold and not when warm
(6 Getting a fuel smell inside the car
(7 Loss of power in acceleration
(8 Fuel leaking from injector seals or injector

Injectors are just as easy to replace as your spark plugs. "
