Re: 1994 Lexus LS 400 ECM

Glowing exhaust manifolds is an indication of rich burning and probably the cause of the poor running. See if you can retrieve any trouble codes from the ECM. But I suspect either a failed O2 sensor a plugged up cat, or a leak in the intake system.

The Traction Control light is also a common issue with those cars. From what I've read, it can be due to a bad speed sensor or an accumulator. But I am not very familiar with this car to be of specific help.

Good luck!
