Default Minifold question

Today I had both manifolds replaced on my 2004 F150 and now it idles low & occasionally stalls. Any idea how to solve this problem? Thanks.

Ah sounds like they left a plug / Vac hose off or summit.

IDE take it back and get them to figure it out.

Possibly clogged catalytic converters? May be causing too much back pressure.

Thanks guys. The truck ran fine last night when I went to work. Seems to have fixed itself. My favorite kind of "fix".

Yeah sometimes computer has to relearn how truck runs for a couple cycles before it's back to normal my old 97 4.6 did that whenever I disconnected battery! Would last couple days then be fine.
