I was driving last night and suddenly saw my rpm going up and down. My engine runs #1 and seems that it only happens once I get over 3000, under that it’s ok. Seems to be electric or something like that ? Any ideas ? Needle ? ---

yeah some more info here. Do you hear the engine oscilating or it is just the needle that goes up and down? I can almost bet its your tach. If you have any type of air flow (ie open windows, holes in the firewall) getting into your cluster then that can sometimes move the needles back and forth. I have this happen when the wind blows a certain direction and my windows are down on the highway. ---

Like I said engine is fine, running A1 it’s just the needle that is bouncing up and down once I get at 3000 and +. I have a disconnected 02 sensor right now but probably not related. Will plug my new one tonight. ---

I have a similar problem but its my speedo thats doing it, if i’m at a standstill with the engine running sometimes it says that i’m going like 40 or whatever, then when i start to move it registers the correct speed.If i hit the gas it goes all the way to 180 also. Probably the same problem just on the speedo. ---

If the speedo’s getting stuck, then yeah that’s what it is. I’ve fixed this before on someone’s 240. Did I mention i’m selling 240km/h speedometers that spin freely (2 left) for $180? 😉
