Alright well i have my 91 tt 300zx. I took it into a Nissan dealership to get it checked out and find out what all the problems were because my car had all of a sudden lost A LOT of power and i didnt know why. They told me that pretty much my entire engine was leaking, #6 coil wasnt firing, and I needed new spark plugs and injectors, but everything else on the car was fine. Now, I dont know what to do i was thinking about buying a new engine, or parting the rest of the car out and having to buy a little beater to get me around . So i need some input and suggestions from everyone because im just really lost and dont know what to do. If anyone could also help with getting a good engine or any advice along those lines let me know as well. Thanks a lot everyone.
