gas and temp gage help!

Both of these are common issues with these cars.

Coolant Sensor: Remove the wire at the sensor on the intake manifold and ground it to the block. It should peg the gauge. If it does your sensor is the culprit. If it doesn't follow the wire back to the gauge looking for any damage.

Fuel Level sensor. The sensor is on the front of the gas tank at the bottom. You will be able to test your fuel gauge the same way.

I'm no expert and someone will probably come along and give you more thorough info. Search these forums as they have lots to offer.
