Just finished with the engine, I went to turn it on after looking over everything, and it was really unstable. It idled horribly, the rpm went up and down like a wave until it stalled. Pressing the throttle did absolutely nothing other than stall the engine more. At this point I dont know what to do. The only thing that come to mind is that I noticed one of the injectors (the one for piston #3) had its tip blown, but I was told it wasn't of importance and I think that piston is firing fine since its heating up the exhaust manifold. Maybe its the timing?
