Talk about beating a dead horse. I believe that I can now take my gauge pod out in less than three minutes. My speedo has not been working, I replaced the VSS, checked the gear box driving the VSS and bought a "working" gauge off e-bay. Still, I just turn the ignition on and it reads 28-30 MPH w/o the odometer turning or the motor running. When I'm driving the needle will bounce from 30 to the pin and at times seems linked to the RPMs more than the speed I'm traveling. I've checked the three connections on the back, good ground, 12 volts and I guess the signal, which my crude volt meter can't read. I'm feeling it's the PCM but +/- $250 just to get the speedo function back kills me. Did I miss anything, or do I just have to swallow the PCM pill? Thanks.
