2002 Chevy Trailblazer Engine Size unknown Four Wheel Drive Automatic 150,00 miles

I used to do repairs back when someone could do basic tuneups. but looking under hood,could not even see plugs,wires,or anything relating.Could you help a former back yarder whocannot afford to take it in to the shop. I feel if pointed in right direction, i should have success.

plugs are on top of the engine,under the coil packs.You will have to remove the coil packs to get the plugs out. I recommend AC DELCO plugs only.
