When you step on it, and the engine rocks forward...be sure to post up your impressions of:
A) the throttle cable pulling out of the pedal
B) the way the car lurches forward on it's own
C) how the insurance company will understand that the car just lurched forward on it's own into the car ahead of it at the light.
Seriously, get a Rabbit cable, build a bracket that mounts to the intake, clip the cable short, and bolt it into what you've made there at the linkage. I'm not trying to be a dick, but iffy fabrication is iffy fabrication man .
