Good idea. I know I've got good fuel pressure all around (had a garage test it for me). If I've got the injectors off, would it be an awful thing just to put new ones on? What's the life of an injector anyway? All of these problems are not temp related. I've got a new CPR installed. Here's another question. On the primary pressure regulator... when you add more washers behind the spring, does that restrict the amount of fuel returning to the tank? > It is possible that you got some particulates in the system while you had > the fuel lines open.
