I'd use a gage and check fuel pressure. Any applicable codes? How long since a tune-up?

The fuel pressure has been checked and there are no codes on the computer it was running good but then it started messing up we put new plugs and wires the magnetic pickup was changed before the truck was messed up I was wondering if it could be the idle air control sensor? We covered one hole for the trottle body and it did not backfire if it could be is there a way to check it? Is there a way to check a map sensor?

What was the fuel pressure spec? When you wait this long to answer back, I get lost. Have a good day.
