[QUOTE="AfricanSnowOwl, post: 16484969, member: 168923"] If I test the O2 pins on the computer they stay at 0.9v, sometimes they'll dip down to 0.8 but it mostly stays at 0.9 which I guess makes sense it it's running very rich. With the vacuum gauge hooked up, I tried isolating sections of the vacuum system and there was no change with the brake booster blocked off. I couldn't get it to do the cylinder balance test, but it seems like it's not just a single cylinder as they all seem to fire. The noid light test was the same on every injector, verified there is spark leaving the cap at every wire. It's the HO firing order, which I've verified and reverified is correct quite a few times. If I rev the engine, it sounds and feels healthy. This is the reason why I understand when people ditch EFI for a carb. I will never do that, but this has me looking at the Holley Terminator X kit.
