This morning as I approached the turn onto the highway, I was nearly unable to stop in time. I pulled onto the road, and since it was clear, sped up to 60-70 MPH and then slammed on the brakes. Sure enough, even with the pedal to the floor, it took a fair ways to stop. Normally when you slam on the brakes in my car, it feels like the world is coming to an end: the nose dives sharply, everything that's not nailed down goes flying, you get thrown into your seatbelt and the ABS kicks in and starts growling. This time, the car just settled gently, no flying papers, no pressure on the seatbelt, and no ABS. I did this a couple times, and got the same results each time.
The brakes still worked adequately to stop in normal driving (though I wouldn't be able to count on them in an emergency), so I decided to drive into town to Jensen to see if I could get it fixed.
As I approached town, the speed limit drops from 55 down to 30, and since I know that area is a speed trap, I dropped down to 30. But my car kept speeding up. Normally, I can coast through town without touching the gas or the brake, but today I was having to ride the brakes to keep it under 40!
I was beginning to wonder if maybe the throttle body was stuck open or something. A fairly easy repair, but I really don't need the expense.
Then I noticed that the floor mat was curled a bit in the corner, and it was ever so slightly pressing against the accelerator. All conveniently hidden behind my foot. Well THERE'S your problem! I'd been trying to fight the engine for the past several days.
Then it fell into place, I wasn't getting stuck behind an endless string of slow idiots on the freeway the other day, I kept having to ride the brakes because the car was accelerating!
Hey, at least it was a free fix.
