My car problems all started about a month ago when I was driving and
then I noticed my temperature gage was rising rapidly. I pulled over
into a gas station and noticed there was no water where the water is
suppose to be.I went to a service station and they said all that was
wrong with the car was that I had a faulty cap, so I replaced it, then
my problems started

   Now my car is having some major problems. In the morning when I
start the car, it starts fine but then it starts vibrating and kind of
studdering. Then it sounds like it’s accelerating when I don’t even
have my foot on the peddle. That’s one problem...

Also the car is guzzling coolant, any reason why?

Please help!
