Several months ago I warped a head on my 94 5.0 and had to tear her down to fix. Went ahead and rebuilt the entire engine from the ground up. Now, I've set timing before, I'm well aware to bring up number one, stab the distributor where the pointer points to number one. Did all that. What I didn't know was to pull the "spout connector". Every time I'd get the car started, it would hit like 1500 rpm for a few seconds, surge a little then die. My timing marks were nowhere to be seen. I pulled the spout and the car started up, dead on 0*. But I opened the throttle and it died. My problem is that I can get the car to start but it will NOT idle. It either fluctuates rpm or just won't stay running. It gets even worse if I try to put the spout connector back in. Everything ran fine before my rebuild, so I'm not sure what's going on. I've been pointed towards MAF, TFI and PIP, all of which I'm going to try and check momentarily. Any by experience or help with this issue would be greatly appreciated. I've never in my life had so much frustration with timing.
