Car Idles Better With Spout Out...why?

[brentwoodboy]

I've recently been tackling a few idle and rough running probs, I put in a new fuel pump and that fixed it. Anyways, my car tries to idle real high (800-1000) and I tried the mechanical idle sequence, but it just doesn't like to idle at 600-650. Anyways, when I took the spout out, it cleaned up and idled smoothly, it still stumbled every now and then, but it was smooth. What do I need to do, leave the spout out?

Make sure your timing is correct. Make sure the balancer isn't spun (if it is you can't set the timing).

Do you have any codes?

What SPOUT out timing does it idle well at? I have a 94GT with AODE and i ran it locked out at 24* for awhile - i thought it ran better that way. I have since gone back to running 8* base timing, but with computer control of the timing (I was not wild about not having timing pulled during shifts).

As wisely said by Rootus, really check out the balancer - otherwise your frame of reference is skewed.

Good luck.
