ok, so my buddy put about $70,000 into his rx-7. let it sit in a garage from january until july. the car started and was able to drive about 35 miles and then it died the second we got it into our driveway. the car has a small battery and has to be jumped to get the car to have ANY power. then when turned, the engine makes a bubbling sort of sound. i believe that the fuel injector is letting too much gas through and flooding the engine. how do i fix this?

thanks......jakes
