Sounds like some of the wires might be out of order or your time is off on the engine

1991 f150 idles rough but when u give it gas it gets better


Here are a few things that might help.
1. Check your spark plugs. make sure the gap is right and they are not worn out.
2. Check your distributor cap and rotor for build up on the contacts.
3. Check your spark plug wires, make sure they are on the distributor and spark plug tightly. also check them for damage ie. heat, knicks, scrapes, etc.
4. intake idle control valve. these do cause your symptoms and are easy to replace.

hope this helps ~ Zach

Ford 1981 f 150 not running changed Coil distributor cap Roar arm plug wires did not help started bur ran extremely rough then died


motors need 3 things to run properly. gas spark and compression. the starting point. also spark timing.
the motor you are dealing with is easy. i just rebult a 1978. anyways sounds like a timing problem . first i would check the distributer. if all is ok spay a squirt of starting fluid in the air filter, or even wd40.,,,,,,,see if it is gasoline problem. isolate where the problem is.

Had work done on my car (36K miles on the car): oil change, new plugs, new plug wires, new dist cap, new dist rotor, fuel filter, pvc valve, and brake work. Now it runs like ****. rough running and exhaust...


Sounds like a fuel mix problem possibly the oxygen sensor. If it ran like this immediately after the new plugs, I would check to make sure all the plug wires are on the right plugs and secure. Good luck!

1991 F150 quit running


You need a new distributor. You've replaced everything else. A distributor will get up and running again.

Sudden loss of power, Backfiring, starts then stalls


Your timing belt could be broken. You want to have this checked as soon as possible to prevent any further engine problems.
