In today's video I will show you step-by-step how to repair the spark plug connectors on a 2004 Lexus GS 300. This is a very common issue on the 2JZ-GE inline-6 engine. The connectors are located in a valley in the engine bay and the constant heat causes the plastic connector housing to become brittle and break, leading to loose connectors and possible misfires.
You will need to remove the throttle body assembly to access the spark plug connectors on a 2nd gen. Lexus GS 300. I cover that in another video:

This method should work for most electrical connectors used in Toyota/Lexus models. Remember to check wiring and take pictures before removing wires to avoid possible errors in reassembling the wiring.

Thanks again for the great content. 🌟👍👍I actually put spark plug heat shield over my new one's.🏁🏁🏁🏁👍👍

[@theautochap]

That’s a good idea, definitely will help with keeping the connectors intact for longer! Thanks for watching! :)

Thanks Chap! I don't have a need to do this, but glad there is a video for this. If possible, can you edit video description to include the part number? 🙏😎🙏

[@theautochap]

Hi Pale Rider, i actually put it in the description, under the ‘part required’ section. You’ll need to click the ‘more’ button to see the entire description. Thanks for watching! :)

@@theautochap Thanks! I must have missed it. :(

Thanks for the video !!!!!!!🏆🏆🏆 I have an 02 GS 300 145k and want to ask, was it the codes that made you want to change coil pack or did you notice this the worn connectors? Is any performance issues associated with bad coil packs? Thanks Amazing video

[@theautochap]

Hello! That’s a good question. I did get a misfire code on one of the cylinders but it was due to old spark plugs and not due to the connectors themselves. I just decided to do the connectors since I was there and if they became loose in the future it would be a pain removing the intake to get to them again. Thanks for watching! :)

Do you know how to get a caster arm that's 2 degrees off, that's not bent, nor worn bushing back into spec?

[@edortiz536]

How do I determine which wire goes where on the new connector if the old connector completely disintegrated? Thank you

[@theautochap]

Hi Ed, on the new connector you will be able to see numbers designating the wire number as I show in my video. Thanks for watching! :)
