I am new to this site I just got tasked with trying to fix my mothers 93 F-150 4X4 the truck is in mint condition and I don’t believe it has every been put in 4 wheel drive that I know of, she has taken it to several shops to fix a rough idle and surging and it will shut off at a stop light but will start right back up, I am a novice mechanic and do not have any diagnostic tools, I have been told it could be a weak fuel pump or something in the distributor, I just replaced the dead battery and it started on the first turn but was idling very rough and sputtering when I gave it some gas, would like to know what you think before I start throwing parts at it.
thanks

 

Take it to a local autozone or advance auto because they will hook a diagnostic scanner up to it for free. I say clean or replace the IAC and check for vacuum leaks. There's numerous threads involving those two, so search around for them.

 

I second redneck f-150. I work at advance and our obd2 scanner is vague but will at least point you too an idea of the problem. Only catch is 96 and up only thanks to good ole obd1 pre 96

All you need is a paperclip, or you can use one of your moms bobby pins.
