Leaky Injectors, 305 vs. 350 Injectors
Hi all,
Have been having hard start problems lately so I decided to check out the injectors. Pulled the plenum and lifted the fuel rails and I physically watched at least 3 of the 9 injectors dripping fuel out when the car is shut off. Luckily it doesnt appear that the cold start valve is leaking down. At any rate, I am going to ship my injectors out and temporarily throw a set of 305 injectors in that I have on a TPI setup that I have in the garage. How much difference in performance will I notice? Who knows....the way these injectors in there are maybe it will be better?
