Rough Start, Idle, Limp Mode After Highway Cruise

[yamahaSHO]

From my findings, it was my Morimoto lights. I swapped to OEM LED and havent had the issue. What I determined (with assistance from morimoto) is that each time my hazards "flashed" it re-activated the startup sequence in the lights, and since it kept getting cut short, it threw a fault code to the computer. I think the piling up of these fault codes with more than a few minutes of hazard time it trips something in the computer & sends the truck into limp mode.

All I know is, it hasnt happened since I switched to OEM LED, and I dont think I'll EVER use an aftermarket light again. The electronics in modern vehicles are too touchy. Not worth bricking a $35k investment.

Funny, I brought this startup sequence thing to them today and "it's normal". I'm with you... OEM is the way to go. There used to be a time when the aftermarket filled the void, better. That's extremely rare now.
