Unintended acceleration & slow start

Hello! I hope I am doing this correctly. My husband and I bought a 1995 Ford Crown Victoria not too long ago. We have already had to replace the brake lines 2 times (well, first the front and then a few weeks later the back). It has had nothing but problems. One thing is the air conditioner, but that probably just needs charged.

Now on to the bigger problems. All of a sudden we started having unintended acceleration. It is strong enough that if you don't have the brake pressed hard it will move your car forward every 5 seconds. The engine revs up on its own. This happens every time we stop anywhere. Including when I was pulling into a parking spot last night. I went very slow and as I was turning pressing on the brake it revved up and I thought for sure the way it jerked, it was going to go over the curb into the road. This scares the crap out of me.

Also, we have a problem with the slow (very slow) start.

Does anyone have any ideas or have you heard of this happening with crown victorias? I know they had a recall on the cruise control, but I have not heard of any recalls on this. However, I did read somewhere about accidents happening due to this and something about it had to do with the way Ford build the car.

Thanks ahead of time for your help. :)

The slow start may be due to a weak battery.

The unintended acceleration can only be caused by one of three things in your year Crown Victoria.

1) The throttle return spring is weak or broken.
2) The Idle Air Control (IAC) Valve is sticking.
3) User error.

#2 would not rev the engine very high at all, definitely not enough to overcome brakes. This usually causes other issues, also - such as erratic idle RPMs and, most notably, stalling.
