Yes, I removed the intake manifold, I replaced the O-rings for the cold start valve, idle speed motor, the 6 main-o-rings, the two o- rings and spacers in the the U-pipes, the gaskets for the U-pipes, and the main gasket for the air meter unit. To clean the injectors, i just sprayed them with carb cleaner to get the deposits off the sides, i was careful not to get any debris on the ends. I reused the old injector retainer clips. I have not checked the timing yet, I will do that and the spray test you mentioned. Thanks for the help!
