Newbie needs help

My 87' f150 (5.8L H.O.)has an idle issue...it starts fine but my idle is super low! So low that when I stop at a red light or stop sign I will put it in neutral to bring up the rpm's to keep it from dying! Blinkers wont work and oil guage jumps all over when RPM's are low. Please help!!!!

Must be F-in nice....lol

I mean, you have a short or long bed and everyone is like "Wow...same truck as the OTHER 1 million made just like it..."

Buy a Flareside and people are like "Well, now that's a bit different..."

Buy a TRUE stepside, as you have, and people are like "DAMN I WANT ONE!!!"

Is it 2 or 4 barrel?
My 351w had a ****ty Motorcraft 2150 that my dad had put on it with pencil lead sized jets, just to "get by with"-Yet I never did get the opportunity to trash it......I am not kidding, the carb says Nov-69 on it, which I am taking to be it was made in November of 1969-

IIRC it came from my neighbor that drives a 78 F-100 DAILY at about 35 mph....

I don't have any hands on with the later model carbs, I know they put plastic over the air -fuel mixture adjustment screws, but I think it should have an adjustment on the idle speed.
