reattaone

HELLO, IN THE MORNING WHEN I FIRST START MY CAR THE TEMP WILL BE AROUND 110 DEGREES. BY THE TIME I GET TO THE END OF MY ROAD ABOUT 1/8 MILE IT IS READING 'HOT'. I CHANGED THE TEMPERATURE SENSOR LAST NIGHT BUT THAT DIDN'T CHANGE ANYTHING. WHAT SHOULD I LOOK FOR NEXT?

I just got my first Reatta last night. Waited 20 years to get one!It is a 1988 , one owner very nice condition. This is my problem - the man I purchased it from told me he had the monitor replaced about a year ago. It worked fine last night. Now today it will go all out of wack for a while then straighten out again. Looks like it needs a horizontal adjustment. Do you think it is bad or there is just a loose connection?
