How to replace ignition coils, Spark Plugs and wires 2002 Mitsubishi Lancer 

Awesome +Cole Hart so glad and thanks so much for your comment :)

Awesome, you got this! So glad it was helpful :) Let me know how it goes

car is all fixed, thanks a bunch!

That's fantastic :)

Awesome Nathan Justice That's what fuels me to keep learning myself and making videos. Thanks!

Good stuff man.

Thanks so much Jose villagomez, I've got some new ones in que I'm excited about :) Be sure to subscribe to stay updated

It's pretty common for these engines to idle rough and weak. If it's really bad, I'd check the motor and transmission mounts and see if they are tight and not busted. Thanks!

Sounds like either a bad spark plug or dead coil.

Haha I love it! Thanks so much for letting me know. Glad it's been helpful :)

did you ever get it fixed? im guessing it was the ignition coil possibly?

Hi. I think that sounds like an issue with either the new plugs or coils. Can you ensure the coils are plugged in the proper order and all making good contact? Also ensure that the new plugs are gapped to the correct gap?

@@mci2727 I didn’t replaced anything. That’s the weird part. I just placed Back the old parts. I just bought the car and wanted to check the sparkplug. But once I pulled out the coil pack I realized I did not have anything to get the sparkplug out…. So I placed the coil pack back. But now it won’t start anymore😬

Hey Ray Bohn I'm sorry I don't know off the top of my head. Should be easy enough to look at the spark plugs and see if each one has a coil sitting on top of it or trace the plug wires back to the coil packs and see if it has 2, 3, 6 etc Thanks!

That's a great question Dj Parsons, thanks so much for asking! The reason to add a after market grounding kit is because over time your factory grounds can deteriorate and break down. This can cause loss in power, radio noise and even vehicle fires. I added about 8 new grounds to different places and the one on the coils is to make sure there's a good ground going to them for the best spark. It more preventative maintenance than anything. Thnaks!

Micah G Robinson Would you ground both coil packs? If I were to replace my coil packs with performance rated ones would I a ground still be purposeful?

+Jordan Valdivia Sorry for the late reply. My first guess would be to check for check engine codes and replace the spark plugs. But aside from tuneup I'm not sure. Have you figured it out yet?

+Micah G Robinson hey bro no problem. i changed the plugs and there is no engine light on or any codes popping. replaced the O2 too. its only on take of that it has no power like wants to die. but once its going i can press jnto the gas and it goes great.

Man, I'll have to think through that but nothing is coming to mind as to what it could be yet. May find a Mitsu mechanic to look at it. Could maybe be a bad gasket on the intake side or exhaust possibly too I'm thinking. But not a issue I have a lot of experience with sadly.

+Micah G Robinson no problem man im still looking into it brotha. but youf videos were alot of help so thank you. keep you posted on what i find out.

+RyTakGaming thanks man i am actually laughing hysterically because i went to find this comment from you thay i got and never looked at, funny thing is that i am replacing them today. let yiu know soon ic it fixes.

Hey +nelson arias Thanks so much for your comment You'll be just fine to go to a junkyard and find the connector and cut the wire long and then just splice it on your car by cutting the connector off your car close to the coil (so there's plenty of wire length left) and splicing it in. Make sure to match up the contacts and see if the wires are the same color and if they aren't match which will go to which.

If you have the money, it's a good idea to replace both if they're both old. Alternatively you can check and see which one is bad with a multi-meter and check the OHMS and compare it to what they're supposed to be. That will tell you for sure.

Micah G Robinson Thank you very much for answers. You helped me a lot

so glad. Hope you get it figured out. Let me know what you wind up with.

Yes, 2004 and 2005 use the same part. Good luck

A bad ignition coil could for sure blow a fuse. It could be any number of things though unfortunately. What fuse is it?

Not sure but ive got to go look for myself so i know exactly whats going on and whats not. Ill get back to you. Thank you so much!!!

You can test the ohms through it but honestly I've always just replaced them and see if that fixes my issue.

For sure it could be If you can find a download for the service manual you can find what the resistance should be through the coils and test them

Aight thank about to get some new could now and try it again thanks l appreciate it will further update u on how it come along

Coil *now

james3000gt There is a way to check with a multimeter checking the resistance of the coil. I don't know what it should be for your car... here's a video that explains this method; ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-UxcO9d9FATs.html You could also buy replacements and replace yours and if it doesn't fix you problem return them right away to your local shop you bought them from.

For sure, glad it was helpful to you! Have a great day :)

Interesting, I'll have to try that. Thanks for the tip :)

I've been happily using anti-seize on spark plugs for over 15 years, never had a single issue. The times I don't use it I regret it (if I have to take them out down the road). No issues. Thanks
