No code 44. Code 13 everytime. I thought about the decelleration but I figured the throttle position switch was the circuit path for the ECU. I know from experience if the TPS is messed with, there are major changes in engine operations. In this case with the speedometer on the disabled list there was no change in engine operation at all with the added benefit of no blinking "check engine" light. It's gotta be something with the connector or the wire if not the O2 sensor itself. I'm sure the speedo has some "close circuit" function for the display because sitting in the driveway in neutral I can't get the check engine light to blink no matter what rpm I'm revving. It's only in motion that it happens and now I know it's only in motion with working speedometer...
so close....
