not hitting on all cylinders

I have a 96 century that is missing on # 6 cylinder I have changed all pugs & wires & it has not helped any suggestions? thanks

injector, check the compression

Ditto the injector. Try a couple of doses of fuel injector cleaner. Put both in at the same time, the 3.1 engine is known for this issue.

Coils onthis car fire 2 cylinders each. So a coil usually will not cause one cylinder to miss. Perhaps if the plug wire connector broke off. :-)

Right if the coil were bad then two cylinders should be misfiring. Also physically check the spark plug and make sure it isn't fouled or damaged.

do a compression check . if ok then sounds like a vacuum leak . normalally its the coil pack .remember if compression the gas then spark if all then it should run.
