just a shot in the dark but hows the timing?

7upedition

timing as well as the fuel pressure regulator... do you have a liquid guage on it? what psi are you sending (38psi)?

Have you tuned it up with new plugs, wires, cap/rotor, timing adjustment, set TPS base idle, clean TB, IAC, etc. ?

Heres a link to fixing idle issues ....http://www.muscularmustangs.com/maintain.php

Check what the EEC-IV is trying to do or logging as failures, run a DIY KOEO/KOER self-test combo.

you cant install that monster without setting your idle high first.

set it to like 1000 rpm,

2.Your EEC needs to adjust to your new setup.


3.Now turn the car off, and unplug spout from dizzy and set timing to like 16*, you want to start a little high then work to where you car does not die.

Its gonna be a tradeoff.[&:]





oh yeah should have your tps set to 1.00 or .99 at idle is cool
