June 2008 in Seattle was a very hot month. Not hot enough to want A/C, but hot enough to give the MPV TT some running issues.
Sitting in traffic during the heat allowed the engine bay to fill with hot air, and this posed a problem to my air intake setup. It would suck up the hot air and begin to misfire. One day got soo hot that I had to abandon it in a business complex and come back later that night to retrieve it.
