I have a glowshift oil press gauge and it seemed to work fine for the first few days but now the numbers jump much higher. It sits around 30ish when started or idle but on the highway about 60 70. Lastnite I was driving and my meter shot past 130 140 150 and was resetting and all kinds of crazy. Any ideas?

 

Was it moving really fast, so fast you could hear the needle moving swiping back and forth?

 

its digital and the numbers would jump crazy high and if i stop it would go back to normal

 

check the ground on your sensor, glowshift's screw terminal sensors tend to come unscrewed, then your screwed

 

Exactly what I was gonna say.

If you can. Solder.

 

I have my oil pressure gauge and air fuel gauge on the same ground do you think thats also why my af gauge needle doesn't move as well as my oil pressure gauge acting funny?

 

If its not the best ground then yes. Gotta get a good solid ground and at best solder if splicing two wires together...

However it doesn't matter how many ground wires you have going to one wire to a ground.

What I'm trying to say is consolidate your grounds close to the sensors then use 1 wire to ground all.

 

Thank you haven't been on here due to work but I will check that out.
