Try checking your gas filter/inline fuel filter. Could also need a carburator adjustment

Speedometer stopped working.

The speed sensors will not fix it. This is something that these cars will do in hot weather. The instrument cluster need to be removed and the contacts from the printed circuit to the connector need to be cleaned. Over time they will lose contact and affect the fuel gauge or speedometer. You may have to replace the speedo cluster. Sometimes if you hit the dash just above the fuel gauge it will start working too. Been there done that, fixed mine as the printed circuit was coming apart at the harness connector.

I have a 1990 Lesabre and the heat/AC fan usually will not turn on ecept sometimes when I hit a bump in the road. Thanks.

You need to replace the blower motor. Its on the firewall right side. OR maybe a loose wire on it. Check your fuse box also.
