Summer is back here in Las Vegas and we have already hit 106F.  With this temperature it brings new issues and some old ones back to life.

For this car when it gets this hot outside the car continues to run more and more rich until it stalls out and won't restart until it cools down. I've check and double checked all the basics and found nothing, until I put my hand on the VEMS itself and almost burned myself. With my temp gun I found the temperature of the VEMS at 156F outside on the case. I grabbed a fan and put it on the VEMS and watched the lambda reading come back to normal.  These extreme temperatures have to be causing a big problem with the electronics. Does VEMS do any type of weather testing? This problem has been here every summer and I've finally figured it out. I'm not sure how I will do this yet but I was thinking about getting a small computer fan and using one of the outputs to run this little fan in the case over a certain temperature.

Has anyone else run into this issue before? Am I crazy?

Definetaly post this on the Wiki itself, 156°F is MEGA hot for an ecu and borders on component problems.
