Hello,

I just had my broken spark plugs replaced by removing the heads to due this. Now my speedometer works intermittently and sometimes does not seem to work at all. The odometer works but the speedo needle sometime used to work intermittently and other times stays at zero or gets hug up at approx. 40km. I hooked up a scan tool and a laptop and it shows that the speedo on the laptop is working. Is my problem that I need a new cluster if the speedo works when a scan tool and laptop are used to view speedometer on the laptop?

Or, any other suggestions to look for what could have been disconnected or damaged during the recent top end of engine tear down and re install due to broken spark plugs replacement?
