Re: S300 intermittent issue
Check the ecu grounds in the engine harness, and any other grounds you can find.
Make sure you are using Resister spark plugs (R in the plug part number, like BKR7E).
If you have a jumper harness, it may be of bad quality and have a bad wire somewhere.

Re: S300 intermittent issue
I'm thinking it may be a bad wire in the jumper harness, I discovered if you more the ecu the car almost dies.
Re: S300 intermittent issue
That sounds very likely.

The jumper harness has seemed to fix the issue. Thank you guys for the help.
