I have a 2004 Chevy Tahoe that the oil gauge bounces around when driving down the road. When it is at idle it appears all is ok. I have replaced the oil sending unit with a new one from o'reilly auto parts and still had problem. so I replaced the dash cluster with a rebuilt one from Dorman and still have the same problem. I have put about 600 miles on vehicle with this problem going on. There is not any noise in engine It runs fine. Any suggestions out there?

Can you explain what you mean better? I would love to try and help but I don't fully understand your issue. Also can you tell us what numbers it reads and such.
my tahoe oil gauge needle bounces around from when driving down the road. when i am idling the gauge reads a steady 40psi as soon as i drive down the road the needle starts reading all over the gauge but never pegs out but will fall to 0 and low oil pressure will light up and then may go back up to 40psi I replaced the oil sending unit and that didnt stabilize the needle so i put a rebuilt cluster from Dorman in and a still made no difference. the oil gauge is the only gauge that is malfunctioning. I know the pressure is ok because i have made a trip of 600 or so miles on the interstate driving 70 mhp and there isnt any engine noise. the vehicle runs great!
