I've got a 1999 toyota corolla with over 170K miles, and I've had my fair share of problems over the years. Currently, I have this problem that my car seems to hesitate accelerating when I first start it. It seems like it wants to idle out. I've only noticed this problem in the past few weeks or so. Nothing significant has happened in the past month to cause it, like an accident.
Someone (not a mechanic) told me that the problem may be the transmission, and may be related to the way I shift my car into drive. Admittedly, I don't always depress the button to shift from park into drive and just forcibly push it down without pressing the button. I don't think it can cause a problem in the transmission, much less this problem of my car trying to idle.
Any help would be greatly appreciated.
