96 rev up and very rough idle after
pretty much what the title says. if i rev the engine even a little at neutral ill get a rough idle. if i rev it harder i get a very very rough idle for a longer period of time. like the truck is about to fall apart haha..but no joking here. this is definately not funny considering i just bought the thing and owe a good bit on it still. second i made a 4" intake for it and this is when teh problem became very noticeable so i took that off and put the stocker back on. please help me with this as much as possible. im by no means a mechanic but the info definately helps if i have my friend help me through it.
