914 starts then dies Options

[Samnation]

Hi I’m Sam, 15, I’ve been working on restoring my grandpa’s 1974, 2.0 liter, 914-4. About 20 years ago he removed the engine and rebuilt it. It wasn’t touched again until this spring when I became interested in working on it. After a bunch of work on the body and the engine I reinstalled it. It wouldn’t start so after troubleshooting spark, fuel, air leaks, etc. I had it running pretty smoothly. Time for a test drive. It worked fine going around the loop around our farm until I came to a slight hill almost to the shop. Me being 15, didn’t have much experience driving a stick, I killed it. After that it never would stay running again. I pushed it back to the shop. Here’s what it’s doing: it starts, idles very low, but usually will stay running. When I slowly open the throttle it gets to about 2000 rpm when it loses power and dies. Starting it up again takes longer cranking and sometimes a rougher idle. Here’s what I’ve done: The fuel pressure regulator I set to 29 psi, I pulled the injectors and they all seem to be spraying nicely. The spark if fine too I think. With the fuel pressure gauge on I was able to see that the fuel pressure does not drop before it dies but immediately after it dies the pressure goes to about 19 psi and holds there. I don’t think the injectors are leaking, I couldn’t see them dripping anyway. The part that gets me is that it was running fine before I drove it, something must have happened there. I would appreciate any help (IMG:style_emoticons/default/smile.gif)
