I hate to sound stupid, but where are the spark plugs on the 2003 4 cylinder? I'm trying to find the wires to follow, but just can't see them............maybe I have "brain freeze"!

 

lol.. no not a brain freeze. The I4 uses coil packs so it is a bit different from the "norm". You will find them here....

 

Thanks so much for your help.......................I had my head in every spot around the engine and didn't realize they were right on top! I had a '94 Pontiac Grand Am 4-cyl, and they were under a cover with pre-wired boots. I thought this was something similar. Thanks again..............
