Rough idle fixed?

[evanj5]

Sooo...my truck now and again would kinda idle rough...wasn't nearly like it used to be.....so I started with plugs and found that it still had the original factory champion plugs and were wore the **** out....so i replaced them with the auto lights and so far what a difference.... Idles just as smooth as it used to..

Mine had about .130/.150 gap when I replaced them. Spark had to get a running start to jump.

Now that I've been able to put a few miles on it since the plugs I think I'm going to do coils to...although it is ALOT smoother I think it can be better

I wouldn't bet on coils changing anything. They are usually good or bad no in between. Cleaning throttle body, cleaning injectors, might help if everything else is OK

How bad is it to change the fuel filters on these

Any recommendations for cleaning the injectors...
