Q: My truck accelerates unintentionally when pulling into parking spaces or garages. This has happened twice.
When tapping the gas, the engine will rev and a huge jump in acceleration happens. I wrecked it the first time it happened because I was pulling into a parking space and had no time to stop before it jumped the curb and hit a handrail. Then I take it to a body shop to have it repaired and they almost went through their garage while trying to pull it in. I want to know what could cause this and how can it be diagnosed.
My car has 48000 miles.
My car has an automatic transmission.
