quick question i just picked up an 87 na rx7 with a street port done to it the car sat for atleast 2 years before the motor was installed now here is the problem the first day i went to start the car it fired up no problem but would not idle and was very slow getting up to speed. now when i go to start the car is just smells like a bunch of fuel but it wont start at all anymore. another thing i notice was when you turn the car to accessory the volt gauge jumps to 12v then drops to 9v then drops to 6v then jumps back up to 12. i need help bad what can be the problem all suggestions will be tried
