Don't use anything but AC Delco 41-103's TB's love these. You can get them at the dealer, but can get them cheaper from someone like Autozone. Our TB's don't like the normal replacements you find at autoparts stores.

2004 monte carlo ss 3.8 engine diagnostic message "cylinder 5 misfire"- will changing the spark plugs resolve this issue?


it is a good place to start, replace ignition wires and plugs, for that year 3800 i recomend autolite iridium plugs and premium 7MM wires.
once you replace the parts erase the code and see if it returns.
cylinder 5 is the 3rd counting from the left on front of engine.

WHAT IS THE RECOMENDATION FOR A TUNE UP AND REPLACING THE SPARK PLUGS.


I take it you have the I6 engine? Use AC Delco 41-103's for the spark plugs, these engines love these plugs. Other brands MAY cause the engine not to idle nice and smooth. Clean your throttle body with throttle body cleaner, with the battery disconnected, needs to be nice and shiny. Change the 02 sensor upstream right next to the exhaust manifold, that's the easy one to change. Also, replace the fuel filter and air filter. And of course, change your oil, Mobil 1 synthetic is the best for these. Check all your fluids also, like differential, tranny, xfer case and so on. If you do change the fluid in your tranny, use GM's new Dextron 6, will shift better and make your transmission last longer.

At how many miles do i change the sparkplugs and which are recomended


you should check your owners manual for manufacturer recomendations. If you do not have 1 then call or stop by you local dealership and talk to the service manager.

now personally I like the 50000 mile interval and prefer AC plugs.

When replacing spark plugs on a vehicle, you need to make sure that the wires are connected back in the correct/same order that you removed them.

RE: spark plugs, check your owner's manual for the correct part number or equivalent. Sometimes the wrong plug will cause the car to get worse.

Hope this helps.
