Hello,

I am new to the board. Thanks for the site.

I am hoping for some assiatance in diagnosing a problem with my IS 300.

The EFI relay started clicking on and off when the car is turned off about a year ago. I replaced the relay and it stopped for a short while, but it has started again and is getting worse. Has anyone else had this problem? Is there a better part available somewhere? Is there a common problem with the ground that may be causing the issue? Any help is appreciated.

Thanks
