Is the header glowing or the catalytic converter? The distributor has a plug on the firewall that when its disconnected it will disable the electronic timing control in the distributor. It's a brown plug that is specifically designed to be unpluged so you can set the timing to 0 with a timing light then plug it back in and the computer will do the rest.

Set the timing as John said. But it sounds like you have other issues going on. Such as overheating or a restricted exhaust system. Possibly a clogged catalytic converter. Any drivability problems? Lack of power, etc.? -Jim
