Speedometer Issues at Idle

searched and came up with this thread:

at idle my speedo now rises to show 20-25mph when i rev the car while parked. its rise reminds me of how a oil pressure psi gauge moves when engine speed changes.


at speed it appears to read correct mph (yet to be confirmed), its just at idle when i blip the throttle to shift into gear that the speedo ''revs''.


any troubleshooting tips from guys who know what they're taking about would be appreciated

man, i've got the same problem, have you figured it out yet? Weirdest problem I'm also having is when I hook my A/F Gauge as soon as I plug the sensor into my meter the engine dies....???????????
