I also have a 92 F150, and while I haven't had this problem, I would check for 3 possible causes. I would check the fuel filter, a clogged filter can definitely cause problems with acceleration. Also, I would try a good fuel injector cleaner. This would probably be a good idea even if it is not the primary problem. Last, check for vacuum leaks. These are sometimes very difficult to detect, but the vacuum is integral in many systems including acceleration. If you can't hear the hiss of a leak, then try to trace each line (with the help of a good manual/diagram) and checkcarefully for tight connections and any cuts or holes. If you find some, it's not necessary to replace the whole line, just take a small section to Autozone or O'Reilly's and have them find a larger size that you can splice with. Hope this helps.
It could be the voltage regulator.
It could be two things. As you know, the alternator charges the battery so it will not drain. If the alternator is not working properly to charge the battery, the battery will continuously drain. Have the alternator tested at your local Auto Parts store (NAPA or Advance Auto) If it is good, have the battery checked.
The battery "starts" the car...after that the alternator keeps the battery charged. They work together in other words.
The battery will run down and he engine will stop. You will not be able to start the engine. The alternator keeps the battery fully charged.
It sounds like you have a circuit staying hot all the time, like a bad switch or even a radio. Also might have a defective new alternator or battery or both. Start with the most obvious places first. Hope this helps
Possibly a bad alternator. The Alternator charges the battery when the vehicle is running. If the battery is not being charged this could cause the vehicle not to start.
The alternator is part of the electrical system. It is what charges the battery and keeps it charged.
check to see if the alternator is working properly or maybe an alternator wire came loose with the new battery installation.
Have the charging system checked. Possibly loose or corroded wiring, a loose alternator belt, or a bad alternator.
The alternator does. It is what keeps your battery charged while in use.
Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alternator belt. If the battery and alt test ok than check the connections to the alternator and battery. You may also have a battery drain (something that is staying on and killing the battery)
Yes, as long as the engine is running, so is the alternator. The alternator is actually what keeps the car battery charged.
