I am assuming it is a carburated engine. Sounds like the accelerator pump is not pushing the extra fuel when required as the accelerator is depressed. Time to rebuild the carb. The kit will contain a new accelerator pump. Look for a tag on top of the card with numbers and letters on it. It will let the parts house you go to know what specific carb is on the vehicle so you can get the correct rebuild kit. Good luck.

if its throttle body, give it a good cleaning with carb cleaner while its running and hold open the throttle so it wont die. also I would check out the TPS (throttle position sensor) pretty cheap fix.

Idels to high when running


I am going to assume this is a full size Bronco with a 4.9 or 5.0 engine.
The computer controls the idle speed by the amount of air allowed into the intake thru the idle air control valve.
If the throttle body is dirty or the valve fails, or if you have a serious vac leak, the engine RPM will be higher than normal.

Then its got to be a problem with the fuel delivery. You need to check that you're getting fuel from the tank.


1) Does fuel get to the filter? If not, is there an airlock or debris in the fuel pipe
2) Does fuel get past the filter? - If not, replace the filter.
3) I'm not sure if you have a carb. or injectors, but one or more of the injectors could be blocked. If a carb., fuel inlet jet may be blocked.
4) Finally, is the air filter good and clean.

I just had the same issue with my 88 xlt w/351 W it wound up being the MAP sensor and the timing. I would check both of these and see if it solves your issue.
