So yesterday I came to a quick stop and noticed my Immobilizer key indicator on the dash was blinking. I started driving and it went off and didnt come back while driving until a few hours later. Last night is started happening a little more frequently but I did notice it seems to come on when stationary and then once back up to speed goes off.

Some things to note, I tried another key and the same symptoms occur. I also had an issue only a few weeks ago with my modifry IR control "wigging' out and muting and lowering my volume on its own. I corrected this apparently by turning the "mute" dip switch off and repositioning the IR transmitter on top of the headunit.

Last I am running non resistor plugs since I have a Comptech SC and these seems to be the preferred plugs. However these plugs have been in the car for a solid 5000 miles with no issues.

So anyone have suggestions as to what it could be? I'm going to swap the plugs when the rain stops and see if that has anything to do with it.

 

I figured I'd update this in case it ever came up in someones search

I was running NGK 7173 non resistor plugs due to them being highly recommended by other SC peeps and they turned out to be the source of both my immobilizer flashing issue as well as the volume issue with the Modifry DCI. I swapped to the NGK Iridum plugs and everything went away. Most people seemed to have no problems with the 7173 and I'm wondering if it had to do with me running them for over 5k whereas others are swapping them out at 3k.

 

5000 miles is very low mileage to have to change plugs, 3000 is super low. I guess that is what you have to do when you are running FI.
