Recently had some major engine work done on my 74 914 2.0. Car runs great except the temp gauge is acting funny. Sometimes it works fine, sometimes it stops working completely, and, most recently, the needle was twitching slightly in time to the turn signal when it was blinking. Thanks for any help you can give me.
So sorry for my first post. I accidentally wrote fuel gauge in the body of the post instead of temp gauge (which is in the heading). My apologies for sending people on a wild goose chase.

Major engine work should be unrelated to the fuel sender, unless they messed with fuel lines or took the tank out. Easy to pull the sender and give it an inspection and a clean. Make sure the float is moving freely. If it is very old, think about replacing it due to bad gas, corrosion etc. Not sure about the voltage surge from the turn signals.
Just noticed you have temp gauge in the title and fuel in the body. Not sure which one I answered for now.

Could be as simple as a loose connection. Have you spoken to the repair shop? did the condition exist prior to their work

Our 914's are quite basic to work on, you might want to purchase a Haynes or Clymer repair manual for reference

Is it your fuel or temp gauge that’s an issue. The title of your post says temp but your post says fuel.

If it is your fuel gauge, besides checking the sender, have you ever had the gauge repaired?

I've used these guys and they are very good

It's a bad connection somewhere. Very possibly on a ground.

Apologies. Meant temp not fuel gauge.

Appreciate the tip. Yes, I have spoken to the shop about it and they are non-responsive. No, the condition did not exist prior to their work.

What year is your car? What size engine? What temp gauge (factory console gauge)? Pics?

74 2.0 all factory. The car has had virtually no modification.

Check continuity of wire from sender at bottom of engine to the plug on engine shelf. They get brittle from engine heat, causing high joint(intermittent going open)

Like Dave said, check the ground. Run a wire directly from the gauge (-) to the chassis and see if that does it. That’ll give you a starting point if it’s not. (IMG:style_emoticons/default/beerchug.gif)
