2002 Malibu #3 cly misfires on v6
have been told to change the sparkplug,wires,coil,module,&fuel inj.;all have
been replaced one by one to no avail !
Did you visually check for spark at the spark plugs on that cylinder? Did you use a noid lite and check fuel injector pulse on that cylinder? The cylinder needs three things, fuel--spark--compression at the proper time. You need to do some testing. Are there any driveability issues, idle or driving down the highway?
I just wanted to add, any electrical component, if the wiring circuit has a problem, replacing the part won't fix it.
Another possibility is low compression on that cylinder. Check compression.
