Ok, I need some help. I have a 1999 Buick Century 3.2 all plugs and wires have been changed but its still idling rough and I can't figure out why. All plugs are firing well. Car isn't really running rough mainly just when idling. Any help would be greatly appreciated! Thank you in advance!
I've had engine code read, always states misfire on cylinder 4, but its firing well. Any idea as to labor involved and cost of replacing injectors?
 
try cleaning out the fuel lines and injectors for the cylnder or all that are mis-firing. this should do the trick. also rev it up real high but just below the redline. like one 500 RPM below and see if it still does. if not it maybe a fuel pump problem. sheck this out too.
