I'm having a bit of trouble here...
My CAS connecter was old, broken, and the rpm wire came out of the plug.
I got a pigtail, and a green top CAS sensor to test if the sensor was bad as well.
Last night I soldered in the new pigtail, and couldn't get it to start for about a half an hour. After it finally started, the rpm on my tach was 2-300 RPM - but the RPM reading on my SAFC was reading mid 500's.
I swapped out the CAS with no changes.
After some hard praying last night, I woke up this morning to verify all connections again. I started it up and again, idling around 2-300 on the tach, mid 500 on the SAFC.
After idling a couple minutes, it suddenly woke up and idled perfect around 900 on both the tach and SAFC.
I drove the car to work and it only cut out when I first pulled out of the parking lot. After leaving work, it started up and ran fine for about 2 miles, and than again the tach started cutting out, falling down and than jumping back up, but with no change in RPM reading on the SAFC.
I have verified my wiring is good, and no essential connectors are unplugged.
I'm at a complete loss as to what could be causing the RPM on the tach to drop, even after swapping the CAS with no differences between the green/black top.
