Faulty ignition coil?
Hey guys. I was stopped at a red light the other night and felt the GX start to shake and jerk. CEL and 4LO light started to flash. Drove home turned off car and tried to look for something wrong but nothing. So i took the car to the Lexus dealer since it was still under warranty and turned out to be ignition coil #2 that needed to be replaced. Wondering if it's happened to anyone else with a 460?

What year and miles?
Coil pack failure can occur on any vehicle but it usually shows up at higher mileage.

Probably cheaper OEM but stock around $75

Looks like it is basically used on all Lexus/Toyota models.

Be very cautious when removing the COP plug. They can be pretty tight. If you pinch the tab and pull, you may end up pulling the wires out of the terminal. This is very common on the LS430. Your best bet is to use a pair of needle nose pliers to squeeze the tab and pull gently. If you pull straight up, they come right off. Good luck.

Good tip. I am a long ways from doing this but will file this one away.

I've never had one fail on me. Most of my vehicles since the late 90s having similar setup or at least a coil to each cylinder bank.

just asked car care nut and he said when they fail as they are not a maintenance item.

Went on RockAuto.com and there was 24 different spark plugs to pick from, from reg copper to platinum to iridium. I know OE is iridium so is Denso the supplier?
