how much would it coast to fix

Buy if I get it on hwy speed it seems to run ok

Noticed while driving home that my brake lights decided they didn't want to turn off. I've tried googling possible reasons but nothing seems to really lead me to an accurate answer.

I had checked it and i had#7 miss firing....now this week when I started the car....it started knocking

I changed the sway bar, ball joints what am I missing

when the car has been sitting cold, I have to pump the gas pedal several times for it to start .After it warms, it starts quickly without pumping. How do I correct this???

When I turn on my turn signals(either way), the flasher flashes irattically.Sometimes it's ok and then it will become irratic. Is this a problem with the control or the flasher?

I have to stop for it to go off. I drive a little farther and it does it again. Is it a sensor issue?

It's a 1998 mercury grand marquis
It will turn over but won't start
Only the driver side got wet

My interior lights, radio and climate control all shutdown when the voltage spikes. As the RPM of the engine returns to the normal range, the everything usually works properly. Sometimes the ABS light stays on, but will reset when the car is turned off and back on.
