What have you replaced so far to try and fix the issue?

3,935

air flow sensor

I would try to do a full tune up. Cover the bases. Plugs, wires, fuel filter, air filter, PCV. Spray down the throttle body with cleaner. See if that cures the sputtering.

this is everything I have replaced. fuel system, firing system, egr, bypass valve, complete distributor, ignition module, ignition switch, map sensor, o2 sensor. The engine is a new crate motor, I thought I had a intake leak so I replace the whole top end. it run really bad when I first start it up and when I let it idle it will idle up and down like a lope and eventually it will die.. it will run good when it is warm but every time I start it back up it will start to sputter 10 seconds after I start it up then stop after a few min. I was thinking maybe it is getting air in the fuel system. just wondering this bronco has alot of money in it it was my dads so I have to finish it to be restored. any help will help thank you.

Firing order is right on and timing is right on? Have you loosened the distributor and just tried to hand time it by ear to see if it will run better? Check out this thread. Sounds like this guy has same issue as you......... http://www.hotrodders.com/forum/will-engine-run-all-if-its-180-out- 95885.html

If you start it and let it idle in the driveway, will it eventually die?
