| After stopping at a stop sign i tried to accelerate and turn left. my car would not go. so i pressed the accelerator harder and it finally and slowly moved forward. i have an automatic transmission, but it was like i was driving a manual and had tried to start in 3rd gear instead of 1st. it's almost like my car had to catch up for a minute before it would go. it has happened several times since that to different degrees. it is a 2003 with only 41,000 miles and no longer under warranty since i bought it used. i am afraid it will do this on the interstate or when i am trying to merge and could be dangerous. *tr | |||
