Hello.

I am troubleshooting my 89 supra turbo with A/T. I would like to know what is the correct RPM @ 60 MPH with the ECT off. I am getting to different RPM. When my head lights are on I get a higher RPM than when they are off. So i'm guessing my torque converter is locking up when my lights are off, and i can't lock up when lights are on. Weird.... This is cause by a rewire inside the dash that the previous owner did in this supra.

Let me know ...


Thanks
