Finally changed out the original spark plugs on my 2007 LGT.
Up until now, the most I've done by myself was a brake pad/rotor swap. I knew the plugs were a step up from that so I read through this entire thread not once but twice. And yet, I still managed to spend an embarrassing amount of time while making lots of stupid mistakes.
Relatively speaking, the passenger side wasn't too bad. The driver side however, will haunt my dreams for weeks to come. Namely that mofo rear drivers side plug. The time it took me to replace that plug was longer than the other 3 combined!
Of course it was a combination of bad luck and stupidity. Like me dropping my 3" extension into the engine bay. I couldn't for the life of me locate it so had to drive my other vehicle to the local hardware store to pick up a replacement. (Hopefully it pops out on its own without destroying my engine.)
Thankfully, the car started on its first try! The idle was lower than normal and surged a bit but I'm guessing it'll take some time for the ECU to relearn/readjust. At least there was no check engine light!
