But on april sunday 14 2019 my car shows the engine light and the tire control stabilizer at the same time then the car start shaking lossing speed,the brakes getting hard and power steering. . Lucky I went at 10mph to 15mph.the vehicle will be placed in a temporary engine protection mode with reduced power and acceleration.

Technitia found code( p0638 ) active code and (p211935002a00 throttle body carbon cleaning- adjustment and found rubber grommet stuck in the throttle body roved grommet.

I had stopped my vehicle, putting emergency brake on, but still in drive. I stepped out of the car and it began to move forward on its own and I was not able to get back into the vehicle. It traveled quite a distance before running into some inanimate that caused it to stop. It was in a driveway behinds buildings and did eventually cross over a side street before stopping. I don't see why the emergency brake did not hold, even though not in park?
