My 96 ford bronco runs rough on acceleration,idles fine. Runs good under light acceleration but if hit the gas hard runs bad and pops. Changed fuel filter no change.what next?

SOURCE: truck starts, dies. truck runs good some days,bad the next

I had the same problem with My 1990 F150 300 6cylinder 4x4.....I cahnged all the same things you did, finally I sprayed a can of Gumout through the throttle body and it worked and ran great. Now I add fuel injector cleaner to the gas and a regular clean with the gumout and the problem has'nt come back. Good Luck to you and hope it works!

SOURCE: HARD TO START WHEN COLD AND WHEN IT DOES IDLES BAD AND STALLS.

Try replacing the ignition control module it is located under the distributor cap Cost is around $30.

SOURCE: bad stumble on acceleration pops through t- body.

Sounds like the fuel pressure regulator. Could also be that the timing jumped. But I'm leaning towards the pressure regulator. Hope that I could help. Best wishes.

SOURCE: 1990 ranger 2.3L runs rough.at idle and when

There will be an egr control solenoid that allows vacuum to reach the egr solenoid, sometimes it will be called the egr vent solenoid. It is probably bad.

SOURCE: sputtering and hesitating

Try replacing the PCV valve, and spray the carb, or throttlebody, with a good carb and choke cleaner.
