Grille Blocks in the Summer

[99LeCouch]

Wow, those runners are nasty. I wonder how mine are. The car's feeling pretty doggish and getting terrible MPG's right now. Although it was sitting for a few weeks, so stuff's tightening back up in the engine. The grille block helps, too.

I'm replacing the UIM along with the LIM gaskets. No fooling around wondering if it's good enough to reuse.
