I am exiting I26 to get on I85 Business here in Spartanburg. It is Sunday afternoon and I85 is almost empty. Merging onto the Interstate, I sort of push the gas pedal against the firewall to induce VTEC, to demonstrate to my wife (the regular driver of our Ody) what that sounds like. (I had asked her to do an "Italian tune-up" every so often and hearing VTEC kicking in would be a signal of success). As you all know, the Ody can move like a bat out of hell, when pushed hard. I take my foot off the accelerator to ease into the right lane, but the van keeps speeding up. I stand on he brake pedal and at least that slows acceleration down. I stare at the gear indicator looking for "N". Start moving the shifter; next I see is a red "R". I panic, expecting the tranny coming up through the floorboard. Nothing happens. Try for "N" again. Motor hits 8,000 RPM. This can't be good. Back into "D" and more standing on the brake. Finally, the ignition key comes to mind, and I turn the key to off and slowly move over into the breakdown lane. If I ever felt like a total idiot, this was definitively it. This must have happened over the better part of a mile, or even a bit more.
As it turns out, the lower lip of the gas pedal nudged slightly underneath the outer edge of the newly installed Weathertech floor mat and did not come back up again.
This really shook me up. Returning home, I immediately cut out a recess into the mat to allow proper pedal clearance. I will inspect the brakes tomorrow.
