Drilled a small hole in the plastic resonator box right in front of the throttle body for easier CRC product application.

anybody see this before? it's not the battery, it's not the battery connection (ground) or high resistance cables
it only does it when cold, I loose all cluster function, or cluster backlight flickers, radio audio, sometimes hvac fan or hvac digital control reboots.
dealer is ordering a new cluster but I don't think that is the entire issue.

got it back from the dealer this morning, so far it appears replacing the cluster fixed the problem

Well today sucked. Took it in for a vibration around 70-80mph. Turns out we have 2 tires that are "unbalanceable" therefore they need replacing. Also, needed a new battery. Original was just over 3 years old, getting to be about that time when it'll just die when its least convenient. Wasn't really wanting to get new tires right now. I went ahead and told them to replace all 4 and I'm keeping the 2 good ones just in case (they are about 50% tread life). Luckily they are comping me an alignment which helps. Getting the oil changed too because why the F not....
