I just rebuilt my engine.306, BBK SSI intake and throttle body(it is 5 years old but never used) BBK mass air . AFR 185 heads , comp cam and roller rockers, hot coil ,headers etc. It will not idle right. As soon as you fire it up without touching the accelerator pedel it surges to 1500 rpm, then down to 500 and continues to get a little better. When I drive the car it will not stay running when I stop. As far as driving down the raod, it is very smooth and powerful.any on have any ideas?? BTW it is a 1990 lx fox 5.0

See the "Surging Idle Checklist for help with all your idle/stall problems.
The quick and easy way to dump the codes is in there too, and all you need to do it is a paper clip! The first two posts contain all the fixes & updates. At last count there were 24 possible causes and fixes for surging idle/stall problems. I continue to update it as more people post fixes or ask questions.
