Anyone get abnormal problems?

[detroiter]

I was driving today and everything was fine on the freeway. I proceeded to exit and when I got off and came to the stoplight to wait. The car was idling fine but then I noticed the check engine light was on (wasn't sure how long it was on for but couldn't have been for more than a minute or so). When the light turned green and I went to take off, there was no response at all from the gas pedal. Pushed it and held it down even, yet no response at all or movement. Tried switching the gears and everything was shifting in the trans, but still no response from the throttle. So I ended up turning the vehicle off then restarted it, finally it took off when I pushed the gas. Idle was a little rough from there.

I went to the garage when I got home and pulled out the MAF sensor, which is the only thing I did today to the car and double checked it. Gave it a nice MAF sensor cleaning earlier today with some MAF sensor spray. Everything was dry and fine looking with it, so I just made sure it was tightened down a bit and also disconnected the battery to let the car reset itself. Once I got it back all connected, I let it idle for 10 mins or so to relearn itself, then once I made the near hour drive back home from where I was, no check engine light and everything seems like it's ok....very strange Yaris behavior in my opinion.

Anyone have a similar incident or wierd behavior out of their Yaris?

I sure miss when all this electronic sensor,etc BS wasn't in vehicles and it was strictly nearly all mechanical.
