It's starting to get hot out. Last week we hit 108. I took my car out for a spin down to walmart (30 min away) and on the way back I stopped at a stop light. While in N w/ clutch out and e-brake on the car started bouncing from 300-1100 on the Tach. I know the A/C can lower the idle a little bit, but that's just ridiculous.

Things I'm thinking might help w/ the hot weather: STi TMIC, and M1 synth oil (I use GTX right now). An intercooler sprayer will come next after the STi TMIC... and of course that will help. Any other thoughts?
