Question about 1990 Pontiac 6000
I have a 1990 pontiac 6000 le with a 3.1L engine, that the speedo reads double the speed it's going. When the car is reading 170km per hr,it acculey is going 94kmh by the gps. If you try to go faster the govener kicks in and slows you down. I have changed the speed sensor,and still reads the same,then I changed out the dash consol with a used one and it still reads the same.Could this problem be in the main computer it self?

first check to be sure the vavuum lines at the throttle body are in there correct places.
on the main pulley of your engine, the one on the crank shaft there will be a little notch on it. mark the notch with some chalk or a dab of white paint. then loosen the bolt that holds down the distributor until you can turn the distributor. turn the distributor a little bit, snug the bolt up and try it. once you have the car running you will need a timing lite to set the timing to the correct timing mark. which should be 8 degrees before top dead center for you car.

I've had vehicles that have done this in the past. In the meantime, try to get used to using two feet at the same time (one on the gas and one on the break) to keep the RPMs up while slowing down. It's just a temporary fix, and not recommended that you continue to drive like that.
When you have a chance, get a mechanic to adjust the timing 'UP' a tad so it won't stall out.
If the vehicle is at a timing where it SHOULD be, then raising it to fix this problem will also be temporary until the problem can be diagnosed fully.
After all, however, it is an old cheapy right? These are just quick fixes.

The heater core is inside the heater case. It is the same plastic case that houses the blower motor. Usually they are replaced under the hood near the firewall or under the dash. I would look at the free online repair manuals provided by parts stores such as autozone.com . They should have the info you need for your particular model.
