1986.5 Supra, Just bought this afternoon.

Hi, this is my first post, but I found this forum and it seems pretty informative.

I have a few questions about my MK3 Supra, 1986.5. Non-turbo, obviously.

1. The engine will not rev above 4,500RPM. Is this due to anything specific? Something with the computer or possibly a mechanical failure? That wouldn't surprise me since this car is in need of a HUGE tune up. It's got 2004 tags and looks like it's been sitting for a while. It made the drive home, but it's so sluggish it was pathetic... I know the Supra is capable of more than that. Any ideas?

2. The speedometer does not work, among other interior electrical failures. No dimmer lights, but the speedo is what gets my attention the most. I haven't really had time to check anything out that much, I checked the oil and checked the coolant before I drove it home. Still blew a hole in the radiator, but no big deal. Anyways, is there any easy fix for the speedo if it's not the cable? Possibly electrical? Fuse or something.

Thanks for any input.
