My temp sensor seems fine, had a rad failure few months ago so the fluid has been changed.

The TOMS ECU is an entire ECU. It is a Toyota ECU reprogrammed by TOMS. It plugs straight into the connectors, so I doubt there is a duff connection here, but obviously cannot rule that out either.

I'm going to fault trace the ignition system and sparks/coils this week. See what I can find.
I was only telling you about coilpacks since you mentioned them in your post. I agree bad coilpack(s) doesn't seem to be the primary cause of your Supra's issue(s).

Good luck with troubleshooting. If you have the TSRM, I'd recommend following the step-by-step procedures within. Please keep us informed.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
