I changed my plugs today, so needless to say I was laying all over the engine and now my temp and gas guage needles seem to jump all around when the car is running and worse when I accelerate. The temp guage eventually shows that its over heated anf buries the needle. I didn't think it even worked before. The car does not appear to be overheated though the guage reads it. Help! What have I done? LOL ! 86 Z28 305 Carbed 5 speed.

Sounds to me like on the tempature sending unit you knocked the wires around and its getting a bad connection somewhere. How bad does the gas gauge jump around? I know mine jumps around a bit, but thats from the gas sloshing around.

all three of the Camaros i owned have the gas guage move around when I rev my engine, just took that as normal

my gas gauge buries the needle when you fill it up. like it goes way past the F. but its seems to some what work . when you fill it more than 3/4 of a tank thats when it drops. does yours do that

The gas gauge may be normal jumping, I just got the car and only put gas in it once but it looks like the less gas in the tank. the more jumping. The temp thing is all messed up stuck all the way to the right at the moment until the car cools down. Where is the thing I need to fix?
Not good pics but is this the temp sending unit? How do I fix it?

I had the same problem with my temp gauge. It would jump it's way all the way around to the right and get stuck when I would turn the key to start the car. I even had a new sender put in when I did the heads. Plus I tried 3 diffrent gauges and they did the same thing. What I did was get a spare tach from the junkyard and carfuly pullout one of the needle stopers off of the tach. Then I would drill a hole at the edge of the red on the temp gauge and glue the stoper in. So now when I start the car it hits the stoper and then it gose back down to normal and works perfect. I even checked the reading with a scanner. Now my oil gauge is diffrent. It bounces around like once a week, while just driving around. Every once and awhile it would get stuck at the bottom of the gauge. Adam :-)

I believe the temp. sending unit is in the drivers side head, right up near the front. Someone correct me if I'm wrong.

on my old car i crazy glued needles (actual needles) at the ends of the red and 0 on the oil and temp gauges. And my gas works fine normal full and empty but it does fluctuate when you stomp on the gas or brake. I blame that one on no baffles in the tank.

The sender for the gauge is on the drivers side between 1&3 and the sender for the fans is on the passenger side between 6&8. Adam :-)
