Spark plug boot came loose the other day on the way to work. With just over 150k miles on this 2003 Galant it was time to replace them and make sure that everything is in good shape. I've put the last 60k on this car, so don't know for sure when the last time they were changed.
This was way easier than it looked like at first. I've never worked on the COP (Coil over Plug) type of ignition system before, so when that plug wire came off it definitely caught me off guard.
Car is running great! I will give an update on the mileage (which I have been tracking closely for the last couple of months) once I run a few tanks through it with the new and properly gapped plugs.
Total cost for plugs and all 4 wires from Rock Auto was $42.46 plus shipping. They have several brands and levels of "quality" to choose from, so get what you feel is the best fit for your project. Watch what you order. Not all of them are sets of 4 like this one was.

Glad you liked it. I honestly thought there was something horribly wrong until I realized the plug wire was just loose.

18 FT-LBS is the torque spec for the spark plugs FYI, per identifix

Thanks! I'm always extremely careful when it comes to aluminum. It can go bad really quickly if you over-torque them.

Same exact thing happened to me today. I changed all the spark plugs and it's still running on three cylinders so now I got to change the wires...I guess

Yeah, don't know much about these, but the Coil Over Plug setup seems to be real picky if everything isn't just right.

I have a 2007 galant 2.4l 4cyl that I just replaced the plugs on. I bought the NGK iridium with a 0.032 gap but I saw in my manual it was 0.044. Since I replaced them (gap at 0.032) the idle has gotten worse than before and runs rough in general. Do I need to pull the plugs and open the gap to 0.044?

Yes, they need the proper gap so that the spark is larger and hotter.

What's the cylinder order?
@DoItMyselfGarage
@DoItMyselfGarage Год назад
Honestly no idea. I just unplugged the old ones and plugged in the new ones. It's computer controlled and the wires really only plug in one way unlike my GTO.

1 is the pass side 4 is the drivers side. I found that out the hard way I had p0301 so I swapped coils and plus between cyl 4 and 2 thinking they were 1 and 3 I got now change so I checked if fuel injectors were pulsing and they are. At this point I panicked that I may have low compression on cyl 1. I doubled checked online and learned I had cyl backwards so I am hoping its the wire between 1 and 4 that was my problem all along. I dont know why mitsubishi put the coils on 2 and 4 not 1 and 3.
