I think I can safely say it's not the floor mat after last night. I was driving slowly when I noticed I had no acceleration and the ETC warning light was on. The speedo wasn't working before this happened either, but I wasn't driving far or fast so I ignored that (it always starts working again after I turn the ignition off and on again) So I pulled over and turned the key off and on, all was normal again.. A trip to Ford, huh?
