BP dies

[jamesmc]

Got the BP to start. Sounds like a crazed drag car, but I'm assuming thats the open headers. It won't stay running, and dies as soon as it starts. If I give it some throttle, I can rev it but as soon as I let off it dies. Spent all day trying a bunch of stuff, and I'm out of ideas. I still haven't figured out the temp sensors, not sure if that will affect it. Anyone have any ideas?

Idle speed too low? Idle air control? Vacuum leaks? Check the cheap and easy stuff first I guess.

large leak at the intake tubing? the VAF needs constant signal (air flow) to tell the fuel pump to keep working.

Is the MAF tube hooked up? Is the small idle tube hooked up?

Yeah, I completely forgot about that damn IAC tube. Sometimes after wracking my brain, I over-think the stupid things. It's revving at idle, but sounds like theres a vacuum leak somewhere. Thanks everyone.

Glad to hear it's up and running! Sounds pretty good, it will sound (and idle) much better even with just a downpipe that goes a couple of feet vs. the open headers. I need to do a BP car again.
