Hi everyone, I purchased an rx7 in December 2016. The car would not start however, I decided to buy it like that anyway. I rented a trailer took it home one of my friends stated to buy mistery oil and pour a little down the Carb. After a several tries the car turned on when I would hit the gas pedal it would turn off until ultimately stay on. I turned on about a week ago more or less the same way when i hit the gas it would rev up to number 2 then it wanted to turn off so i left it on, little by little pressing the gas pedal more and more until I would rev it up to six. I turned it off and on several times, it would turn on normally. Now I tried turning it on today after a week or a little more it does not turn on. This is my first RX7 I have always wanted one since I was a teenager in Puerto Rico. I Need all the help I can. I live in Newark,NJ. Thanks for your time
