If you can do it yourself, it is not very expensive at all. A couple of dollars for each spark plug and maybe 50 for the wires. I would also replace any other ignition components that are wear items if you are going to replace plugs and wires. My car had a cap and rotor that I also replaced for minimal money. If you have a garage do it, expect to pay several hundred dollars.
how much does it cost to replace 2002 Chevy Avalanche spark plugs, plug wires, fule filter?
i think its around 2oo to 2ooo $
Spark plugs + 30 minutes of labor.
It cost me over $450 at the dealer. This is due to the fact that they must remove the intake manifold to access the back 3 plugs.
Is it running rough? I am wiling to bet you need to replace the plugs/wires. The roughness you experience is the sparking or arching with old plugs/wires. They cost about $45. Use a light coating of bulb grease on the ends of the the new wires, and replace them in the right order.
A local garage is charging me $278-ish for plugs and wires on a 2007 Chevy Equinox today.
The spark plugs for a Chevy Tahoe run between $8 each up to $39 each. The cost to replace them runs between $64 and $312.
There is no plug wires on a J30, you just unbolt the coil pack that's on top of the spark plugs and then change your plugs, after your finnished changeing the plugs you just reinstall all the coil packs on top of the spark plugs, but becarefull you don't break any of your coil packs, they will cost you.
