The only does this in second gear is a scratcher for sure.
Another fine re-engineered item in the fuel supply of this model is the airbox and idle control valve screwed to it. The new box had a lot larger opening and larger idle control valve with tubes running to throttle bodies. I have pictures of both, but on a different computer.
Seems GT's were more prone to a warped airbox...may be the dual air inlets of the S didn't allow the box to warp as badly. Anyways, caused a stall issue more often after a long run. I replaced two on early K12GT's. Neither of our two S's presented that issue.
The stick coils will not show as a failed unit, so pretty much need to either replace all four or narrow down a bad one, which on that model is a PITA compared to a Boxer. The FPC on the R12XX's sat in a well on top of the tank and they corroded,leaked and failed. The location on the K at least has it vertical, so the failure rate is lower.
Never concerned with heat, but we avoided anyplace that the air was not moving if possible on these models
Hope you narrow it down
