Jordan, I hate this stuff, you have to remember that on a car the age of a DeLorean a lot of tarnish and deposits will build up beyond the inline fuel filter. The injector cleaner will release all of this crap and deposit it right in your injectors. I put injector cleaner in my tank whilst at a friends house and then set of on the 100mile return trip, by the time I was home the car was farting around all over the place and appeared to be misfiring on 2/3 cylinders. On testing the injectors nearly all of them had crap spray patterns and leaked, you could even see the dirt in the top of the injectors. They were fine before I put the cleaner in the tank. I really wouldn't recommend using this stuff unless it has been done regularly in the past. Change your fuel lines and injectors (if they are knackered) and forget about it, I would never use this stuff in any of my cars again. Also although you can clean these mechanical injectors, it is normally the spring (which ensures the pressure at which the injectors open) which weakens over a long time and causes the injectors to leak and spray different amounts of fuel leading to rough running.
