Hi everyone, I am a regular user at ffcobra.com. I am buidling a FFR Roadster. I have a 302 EFI. I built it from the block up. I didn't want to re-use the factory harness so I went for the Holley Commander 950. It's really great since it's such a small harness. You hardly see any wires. Anyway, problem is I am having trouble tuning the thing properly. After it idles for more than 20 minutes, it jumps up and down. When I give it a little gas at that point, it wants to stall. I have talked to Holley many times, they always suggest someting different, but it always seems to come back. We have been playing with the IAC alot (Idle Air Control). It seems that when it get's really bad, I get a whistle sound as well. Kinda like a Manifold Leak or something. It's not a leak though. Any help would be appreciated.
