353628 Posted November 26, 2008 Report Share Posted November 26, 2008 The digital speedometer seems to read correctly but the needle speedometer reads about 5MPH fast, anybondy had this problem gauges work fine and needle does not bounce, just reads fast. Anybody had this problem or know how to fix Link to comment Share on other sites More sharing options...
Ed Hall Posted November 26, 2008 Report Share Posted November 26, 2008 It could be a weak spring on the needle speedometer. I also notice the same problem on my 1982 Suburban. The speedometer reads fast however, it keeps me from getting speeding tickets. Link to comment Share on other sites More sharing options...
KHE Posted November 26, 2008 Report Share Posted November 26, 2008 The speedo needle on a '98 car should be operated by a stepper motor. Kevin '93 Fleetwood Brougham '05 Deville '04 Deville 2013 Silverado Z71 Link to comment Share on other sites More sharing options...
