I built a pretty stout TBI and have not been able to work the bugs out until recently.... The engine will start easy and idle well and have good throttle response some times.... But other times it won't start, or if it does it is hard to start and runs poorly......

I recently discovered that with the KEY ON but ENGINE OFF, you can open the throttle and the injectors go crazy and start pulsing..... That can't be right..... THe oil has gasoline in it and the one plug I pulled out was wet with gasoline.......

At the 5:50 mark of this video you can hear that the engine starts right up and idles well and has good throttle response....... So the video shows what this thing SHOULD be like........ Then randomly without warning, it runs poorly..... I'm thinking the plugs being wet must be the problem and I'm also thinking the problem must stem from the issue I describe with the fuel injectors........ Anyone got any insight into this?
